Amazing Spider-Man #252 CGC 7.5 Newsstand Edition

Got a CGC 7.5 copy of Amazing Spider-Man #252 here. This is the big one with the first appearance of the black alien costume. It's a newsstand edition which is getting harder to find in decent shape. The slab is clean and it has white pages. Cool piece of Marvel history if you're looking to fill that gap in your Spidey run. Case is in good shape, no major scuffs or anything.
