Is This Really An 11A?

Color looks played with. Triangles appear solid, not engraved lines.

Is this your image?
Don

No, comes off ebay.

Image appears to be grossly over-saturated, I doubt the stamp really looks like that.; its great when people get a hold of imaging 'tools'.

Removing the saturation and the image looks like this

Either that or its a proof - the India and Card proofs look kind of like the original color.

It supposedly has original gum. Were the proofs gummed? I don't recall seeing a proof of any 10 or 11's.

41P4 comes to mind (no gum though). As far as original gum goes is that what the cert says?

I agree - looks like a proof. Can't put my finger on why I say that, except that when I first saw the scan, I said, "Proof!", without even reading the post. The impression looks tack-sharp, like a proof. I have no doubt that the gum is original to the day it was applied. Was it applied in 1851, or 1951?? It looks like the scan has been worked on - heck, I do that myself for clarity, and I don't use them to sell stamps. If it has a clean, recent cert, I'd pay many multiples of catalog just due to the impression! Then, I'd send it to another certifying body for another cert.

No cert with the stamp in the ad.

Look at the backgrounds of their two images, why would they change the backgrounds?
Don

If they had a scan already lying around of the front, and realized that they had to make a scan of the back would be one explanation.

It looks like a gummed proof to me. Very damaged item.

Perhaps. Their other listings have backgrounds that look like this...

It could well be a proof but my opinion remains that the image has been saturated.

The color of the stamp is probably correct, but the stamp is a proof of Scott 41, probably an india proof. Attached scan is a 41P4 shaved and perforated to resemble a stamp.
