Hello there. New member here. I purchased this cool collectable a few months ago from an antique store here in Hamilton Ontario Canada. They got it from an estate sale. Story goes this envelope was signed in 1990 by Ali to commemorate his 30th anniversary of winning gold at the Rome Olympics in 1990. Apparently only 1000 were signed to mark this occasion. The picture of Muhammad Ali on the envelope is actually silk. The postmark on it reads 05/09/1990. It's framed and has a picture of Ali and a brass looming plate that says "Postmarks of History-Muhammad Ali-september 5th of 1960-- 30th anniversary September 5th of 1990". This was put out by a company called Gateway Stamp Company. This frame and picture with it is custom as I have seen a couple other of these signed envelopes online with different framing styles. As far as I know in 1990 if you ordered this you got the envelope and COA. Any framing was added buy the purchaser after they obtained it. Your opinions on this would be greatly appreciated. I've included all the info I know about this piece. Thank you
