The Brave and the Bold #87

This January 1969 pairing of Batman and the "New" Wonder Woman crackles with racing-circuit danger, as Mike Sekowsky and Dick Giordano's cover puts Batman leaping onto a speeding red race car while a menacing helmeted driver bears down and a bound Wonder Woman lies helpless on the track directly in its path. The story title "The Widow-Maker!" says it all — the stakes couldn't be higher with DC's Dark Knight in a desperate race against a machine that could crush its captive before he can reach her. It's a wonderfully kinetic snapshot of the era's action-packed team-up formula, delivered with real urgency.
