The Spectacular Spider-Man #133

Part 3 and the conclusion of "I Am… Spider!" arrives with one of the most striking covers of 1987 — Bill Sienkiewicz's raw, expressionistic pencils and inks rendering a wild, angular composition in stark black and white. A wild-eyed, disheveled figure in a lab coat is caught mid-tumble while Spider-Man — clad in his sleek black costume — looms in the foreground, gripping what appears to be a large weapon or instrument, the jagged hand-lettered words "I AM SPIDER" slashing across the scene. Sienkiewicz's loose, Egon Schiele-influenced linework (noted right on the cover) gives the whole thing a nervous, unsettling energy that sets this issue apart from anything else on the racks that December.
