Warning: Probably fake GI Joe drawings coming to market

I note that a seller is suggesting they are about to release some GI Joe drawings "signed by the artist"; the sample image shows they're signed by Darrell McNeil. A bunch of these came on the market 8 years ago or so. I bought a few. They do not seem likely to be genuine, and seem intentionally deceptive with production code indicia included on them.

I'm glad I'm not the only one who noticed. I messaged Animation Legends when I first saw their announcement, and have heard nothing back. Since then they've advertised these a second time on Facebook. It certainly makes them look bad if at best they're getting fooled by poorly done fakes.

Hah, looks like I am one of the suckers. I bought this one back in April: http://rubberslug.s3.amazonaws.com/user/a/d33fd8776f84d5883c296de21e9f7e1/m0tg8liyd4_o.jpg

I purchased it from this user: https://www.ebay.com/usr/sudafed24
