Pretty hard to say... In general it looks correct (an exception "y"), but I don't feel comfortable with it. Isn't strange place to put an autograph right here?.. I've never seen something like that.....
Is it sleeve from 45 rpm? Plus, it's hard to see, is it a pen or a pencil? Can you get more quality pic?
Yep, looks good, but I wouldn't buy it... Just I don't like a signed sleeve and the place where the signature located. Maybe I'll change my mind if I'll see pic with better quality... So that's my humble opinion.
