I Know I'm Nuts… 362s Don't Live On Covers Right?

Not the right paper.

Gawllygee it sure looks gray and off; to the other 6c perf12z to my eyeball

It's never the right paper, till it is

How would one approach a watermark with this situation anyways?

Did you put a perf gauge on this stamp? Why would anyone use a 21 year old stamp on this cover anyway? (no, it's not a bluish paper)

Why does it look like it has other partial cancels on it, that do not extend to the cover itself?

They appear to be in the same color, so it might just have been a bit of a kiss with the handstamp when the cover was cancelled.

Don't like the answer? Send it off for a certificate and report back.

I'm sorry what was your answer that you think I don't like?

Is there a reasonable approach to finding the watermark?

Your pictures and statements sometimes don't go together. I'm assuming that you placed another stamp on top to try and show us that they are different? If so, I'm not convinced. Due to environmental issues and possibly storage over the years, I'm just seeing natural aging. No special stamps here. Of course, if you don't like that answer (that you don't have a special stamp), then send it in for certification. They'll carefully remove it from the cover, if necessary. Good luck.

Yeah I'm always petting the cat backwards. I don't mean to pass on the fleas tho. Sorry if I come off rude or disrespectful. Not my intention to agitate

In addition I feel like ALL stamps are special haja we like stamps
