The Batman Family #7

This October 1976 giant-sized issue of Batman Family puts Robin and Batgirl — the "Dynamite Duo" — right in the thick of it, facing off against the Huntress and Sportsmaster in "13 Points to a Dead End!" Ernie Chua's cover captures the clash vividly: Robin and a leopard-costumed Huntress trade blows on stone steps while a helmeted Sportsmaster brandishes a sword below, and Batman swoops in dramatically from above, with Batgirl standing ready at the side. As a bonus, the issue also promises "The Menace of Dr. Double X" and "The Mystery of the Broken Batman Trophies," making this a genuinely packed package from the era when DC's dollar giants delivered serious entertainment value.
