 Art by (and SIGNED in pencil by) Wes Wilson, medium-thick flat vellum stock poster is in excellent (B+) condition; there is a 3/4" tear in the lower right margin, along with a light to moderate amount of handling wear (soft pinch dings and tiny bends), but overall it is in pretty nice shape. 

 UNIQUE-looking ARTIST SIGNED oddball version of the BG 24, complete with a set of cards along the side and a whole other poster on the reverse!
