Upside Down Cow Stamp - Help Please

Hi Everyone,
(I just changed the subject, hoping to get a reply, LOL)

I thought I saw this stamp somewhere here on SCF, but I just did a search using many different key words and I cannot find it.

I've looked at the stamp closely, it looks like a real stamp but what do I know , still has the original gum on the backside. I guess it is a fake or my online librarian skills are off today.

I've taken photos upside down, with the daylight behind, and the backside. Thank you for all who can help.

I'm not a Costa Rica collector but, seeing as your stamp was issued in the 1950's, I think it would have been noted somewhere as having an inverted center? Cannot see it listed where I look though. My stamp looks like this one.

anytime theres a printed center I guess there is possibility of an invert although most would be listed if they are known. A perf check would be helpful to make sure those are correct and a high res scan would also be helpful even though your pics look good. Some forgers would actually print the outside inverted over a regular center but I'm guessing a 1 centimo Costa Rica cow doesn't catalog very high as normal so don't see the benefit in forgeing it. Paper looks really white but so does scotzm's. Holy cow!

That should be 'holy upside-down' cow

Something else is going on with that.
If you notice the cow is not only inverted, but it's also a mirror image of the cow in scotzm's stamp. In other words, looking at the cow right side up on both stamps, one is facing left and the other is facing right.
Something is definitely not right.

Spain,

With inverted centers the cow would face to the left. and the regualr stamp would be to the right.

Appears Spain is right - it IS a mirror image - impossible on a legitimate invert.

Many Central and South American countries outsourced the printing of their stamps during that era. As part of the contracts, some printers requested the overseas printing/reprinting rights after the designated period of use. The subsequent printings were sold outside the country, mainly to stamp dealers. It is known that some of these printings also included batches of inverts, missing centers/colors...

Since the "errors" were not sold through the post office, many catalogs (including Scott) do not list them. But there are collectors who collect them.

This is not to say there are not legitimate inverted center stamps from Central/South America.

I checked to make sure, but your stamp is not listed in the Inverted Stamps of the World Catalog.

Yes, cow is definitely pointing the wrong way.

Can we get a measurement on the actual stamp size, or put samples side-by-side? I have a feeling that the inverted stamp is also much too large.

Scotzm is playing funny beggars !

Nice one.

Londonbus1...now get that cow pointing in the right direction....and no tongue ! ...I said no tongue !

Thank you for all the responses. I am no good at measuring, but I did my best and have included many photos next to a ruler and the stamp gauge but I probably don't have it placed correctly?

I also seem to recall that I have another one of these stamps (upside down cow) one that is used, so that is why I thought that this has to be some common error, but I don't know.. Thank you all!

Looks like it's about Perf 11-11½ from what I see here.

scotzm - looks like your cow drank sour milk!

Scotzm,

It's still pointing in the wrong direction !
