Marvel Treasury Edition #16

In "The Day of the Defenders!", the Enchantress unleashes a spell that transforms Barbara into the Valkyrie and petrifies the Black Knight, setting the stage for a desperate battle. With Omegatron's power dwindling to 89 hundredths, the fate of the Defenders hangs in the balance as Valkyrie rides Aragorn into the fray. Written by Steve Englehart and illustrated by Sal Buscema, with inks by Frank McLaughlin and letters by Artie Simek, this 1978 Marvel Treasury Edition features a striking cover by Gil Kane and Bob Wiacek.
