Bulgaria #c31-Printing Error

Star is missing from wing. Not noted in Scotts or Sanabria. Hoping for a Bulgarian collector for explanation. This is MNH and shows no surface damage.

You really need to post a pic. Also, Scott generally doesn't spend the effort to catalog printing errors for non-USA stamps in any serious way, so no sense ever looking to them.

In this e bay listing one wing with no star...I think this was more of an inking issue..

The stamp which is showed, from eBay and the one you're asking about is from the 1945 Air post . Optd with airplane and O.F. surch issue,Mi #471-476. These stamps were issued in January, 1945 it's purpose was to collect additional funds .They were also used,for propaganda , agitating ,for the new government of The Otechestven Front ( National Front),which back then consist#1077;d
mainly ,from representatives of communist party. They were withdraw,from use in 1948 . Made mostly on 100 leva,yellow,parcel post stamps tath were not issued for regular use without these overprint placed on them.
The stamp ,which your refereeing is Mi #471 ,printed on a 1 lev stamp ,from Definitives of Boris III. The error pointed in your post is not mentioned neither in Sima catalog,Bulpfhila or Catalogue of Bulgarian post stamps of the Sofia Philatelists Association which is specialized in these types of errors.
Most of these have this detail on both sides of the airplane, but there is a possiblete tath this is a rezolt of a small inking error which occurred during the printing process . There are many other similar errors tath are not recognized by any of thrse catalogs . Unfortunately there value is not very high ,only few dollars even in mint condition.

These could be seen with the star on the wing and without it . You could see these on the images below .

These are images of a similar stamps with minor inking errors.
Dash not placed over the leter I ; ,at the stamp in the right .

The dash in the letter A at the top inscription is missing.

Thank you "post pe". My stamp looks just like your second image. It still begs the question: if this is a very common recurring image why is it not acknowledged in Scott's or Sanabria?

Seriously, stop thinking that Scott is a comprehensive resource for non-USA stamps.

If this fell within the coverage range of Scott's Classic Specialized (i.e., through 1940), it might warrant a note. It's just too specialized to warrant a note in a catalogue with worldwide coverage. For example, I don't see it in my Michel Europe Vol. 2...just Mi 471 (with the "typical" overprint pictured).

My Sanabria is 1946, so I can't speak to anything newer. In 1946, they picture the 1945 issues but don't list values or other information. It's pretty good to even picture them so quickly at the end of what had been a very tumultuous time.

To answer your question ,why it is not in the catalog ........simple answer is what your dealing with is FLY SPECKING .
These are variations that are too minor for most specialist and something dealers don't offer or identify as being important . Fun to search for and something to write up for some collectors .......but the answer is nobody is going to pay a premium for ,

post pe, in the picture, the block of Mi 471:

the 2 stamps on the right side have the design shifted up, a bit higher than the left side, and rotated to the right.

Would that be a normal occurrence, as far as you know?

It doesn't really beg the question. First, just because it's common doesn't mean it's noteworthy. Second, it's simply not possible for any catalog to list every color and printing variation of every stamp, it would make worldwide catalogs thousands of pages longer than they already are, nor would there be agreement about what constitutes a noteworthy variation. Consider the Great Britain one pound Postal Union Congress issue from 1929. It's listed as SG 438, Scott 209, Yvert 183, Michel 174. Now imagine SG listing every flyspeck error of every stamp, in addition to already distinguishing some shades and watermark varieties that by the 1929 listings had already added 229 more listings than Scott. Extra wrinkle, third blade of grass, missing mast, broken arch, the permutations are endless. Third, the best and most thorough coverage of a nation's stamp issues is almost always to be found from a native catalog if it exists: few collectors of Japan would rely on Scott over Sakura, collectors of Germany shouldn't be using anything other than Michel, those focused on Denmark and Sweden should have a FACIT within arm's reach.

Redsfan11 ,the post of classic_paper explains all. There are many errors tath are not listed in the catalogs which you're referring .They mention only the most commonly found varietys of the stamps of a particular country,not the smaller ones which can be object of a specialized literature .There are no specific records, for your variety in any of the Bulgarian post stamps catalogs . The error adds some small value to the stamp even if it is not catalogued. In any case you might consider it ,as a good addition to your collection .

These stamps are ,from the Definitives of Boris III, second issue,from 2 September 1940, but due to the historical period in which Bulgaria was at this time, there are many varieties of this stamps . The records of the Bulgarian Post archives indicates the following yares of production - issued in two tirages in 1940,issued in two tirages in 1941,five tirages in 1944. The number of stamps printed, from these tirages is not well knowned .There are many varieties in the type and size of the perforation ,in the paper - with two different watermarks ,without watermark ,on slightly glanced paper, normal, hard (carton) and pelure.
Olso they could be foud in different shades of the colors.
I have also observed the shifting and the rotation in the block.
I don't know what might be the reason, for the rotation of some of the stamps ,but l could guess tath it's some type of defect tath occurred in the printing process. This shifting can be seen frequently in the most of the sheets. Possibly the quality of the work at the printing office was not so good as in other countries.

These are samples of sheets with shifting in the stamps.

The same shifting can be seen on these two blocks.
