Here's another punch from the 1983
Sword of the Atom series by Jan Strnad and Gil Kane, this time from issue 2. Due to Kane's wacky page layout, I had to scan the entire page, but it's worth it to see all this dynamic Gil Kane art.

However, this page does come at the end of the issue, so we're left with a cliffhanger as the Atom is about to get stabbed with an arrow.
