I was at my LCS this summer and I found something in the dollar bin that peaked my interest. There were two random and rough looking Gilbert Perreault autos. What made them different was they were signed Gil. I received my first and only Perreault auto a while back and it was a TTM which cost me 5 bucks instead of his new price of 10 bucks. In that auto, which I am positive it is authentic, he signed it Gilbert. So were these ones fakes, forgeries or the real deal? I did a little digging and it looks like he does/had signed autos at one point with Gil. In fact, his 74/75 card lists his name as Gil Perreault, so it is entirely possible that he did sign that way. I am not sure what time period it was, but some of the older autos I have seen around of his did have Gil rather frequently so I felt confident enough to drop two bucks on these cards and save them from the dollar bin.
I am pretty sure these are authentic...I might even go as high as 90% on that. Of course, I will never really know for sure and they aren't really worth authenticating either. I think the 74/75 is available for trade bait if anyone wants it, I would be more than happy to ship it off for another auto of someone I like or don't have.
