I dunno about this....Where's the COA?!?!?! And comparing that pic to known autographs , they just don't look similar.
Unless, there's some sort of coa specifying the date this was actually signed or a better description and pic of said item I'd do a serious caveat emptor on this piece. Just wrote to the photographer listed for this piece to see what info he can provide.
