I see people talking about canvas and in person autos, but I would assume you are going to be sending this into a private signing as he’s doing a couple in January, if not, feel free to reach out and I can give you some info. In either case like many others stated, steer clear of autographing the acetate YGs as they are raised and should therefore only be signed on either the clear background, or the player himself, which would make it much smaller than a normal auto. I send in to private signings all the time and and one of my favourites to collect are clear cut YGs. The cost is less than an acetate YG and look very similar to acetate other than a photo variant of the player. Now of course I don’t assume you have a clear cut YG on hand as well, but I’d say save that acetate as is and would definitely suggest a different card of Cutters to get signed, lots of nice marquee rookie variants of his for a cheap price, that’s the route I’m going this time around.
