Captain America #190

Cap and the Falcon face an overwhelming threat on this October 1975 cover, where Gil Kane and Joe Sinnott pack the image with a massive mechanical robot assassin looming over the duo as they battle through a pile of fallen figures — with Nightshade visible among the chaos below. The cover promises an "All-Action Issue" as the dynamic pair square off against S.H.I.E.L.D., Nightshade, and what the cover boldly calls "the deadliest robot assassin of all time." Tony Isabella scripts the story inside, brought to life by Frank Robbins and inker Vince Colletta — a punchy mid-'70s Marvel package that earns its action-packed billing.
