My recent education (by responses to my previous posts) on plate block numbers has lead me to another curiosity that I have noticed with plate block numbers.
Now that I am aware that there is an "invisible ... to me" (yellow) plate block number on some multi-color sheets, I have noticed that the two numbers (e.g. 27276 and 27275) are both right side up on some sheets/blocks, but one of the numbers (27276) is right side up, while the other number (27275) is up side down on the same sheet/block. (see attached images).

Anybody have an explanation?

Well I can tell you that the 1st two blocks you posted are the error varieties - the color yellow is inverted. So it would follow logically that the plate number - printed in yellow - was also inverted.

The normal block is the 3rd one you've posted, where everything is correct...

Thanks!

I didn't know that I had both types, since I could barely see the yellow, I never noticed they weren't the same, since I could only see the first (non-yellow) plate block number.

In the coin world they would call these varieties ??? HA!

Dag H error. Bummer for the original finder(s).

Sometimes it is best to keep a current stamp discovery a secret for a while before announcing it for several reasons. 1) To avoid confiscation of the item by the post office or others. 2) To prevent the error from being purposely reproduced to make it common. 3) To allow the finder to find more of the item themselves. 4) To give it some sort of mystery and elusiveness. 5) To avoid it becoming more common as many more go out looking for it and finding more copies around.

After reading the link provided previously on this invert and finding out that it was printed in three different colors by the Giori press, I couldn't help but notice that this same press was used for printing the St. Lawrence Seaway stamp by the U.S. However, only the Canadian Seaway stamp was found inverted because it was printed using two separate printing plates. The finding of an inverted U.S. stamp was dismissed because it was done on a Giori press that only used one plate with different parts being inked separately for the different colors. This now begs the question about the inverted yellow color on this different U.S. stamp.

This Linn's Stamp News October 2012 article explains
why 2 plates were used even though the BEP Giori press
at that time was capable of printing 3 colours (inks)
using only one plate.

Interesting positions are the upper right and lower right ones since you can see the actual outline for the upside down number four.

It is too bad that the finder of the original inverted stamps announced his discovery early to the public which resulted in the post office purposely mass printing the error.

@ jogil:

This seems to be getting more interesting with every post.
With your latest pic addition, there are now three "varieties" posted here of the DAG stamp. (Must have been one heck of a party!)

It is now beyond my understanding of this phenomena as to how both of the plate block numbers were printed on the top right side of the sheet, instead of the top left corner. And also, the yellow number was printed up-side down!

Just rhetorical and interesting point!

Three "varieties" illustrated:

This whole phenomenon has been covered here before. Go to www.goscf.com/t/4938 for pictures of the three possible varieties

Great! Thanks Peter.
Good LINK.
That should rap it up for me.
I hope.
Now the only thing left for me to do is find some matching picture frames.

The anti-glare UV resistant glass is also important or whatever material you choose, acrylic etc.

I didn't fully understand what was going on with the Hammarskjold misprints until I realized that the sheets of stamps were printed in printings of four sheets to a printing. Thus the block numbers are on all four corners of a 200 stamp sheet..
Now I got it! and I made up a sample of what is going on, for my records. Thought I would share it with any new comers, etc.
