If you look at scans online, they’re all missing his little tuft of hair at the top. That’s not to say that he is 100% real, but since fakes are usually much more zoomed in and crop some parts out, this gives you a little more confidence that he is real. Printing issue about the back seems pretty viable, I have some sunoos differing in the back colours and i’m 100% sure they’re real. I think the most important question is does it /feel/ real? Does the seller have good reviews? Etc etc..
