Batman: Dark Knight of the Round Table #1

Part of DC's Elseworlds line, this 1998 Book One of Two drops Batman squarely into Arthurian legend — and the cover by José Luis García-López makes the most of that mashup, presenting a battle-ready Dark Knight clad in gleaming medieval plate armor, bat-eared helm and all, sword raised against a backdrop of a brooding castle, swirling bats, and a rearing silhouetted horse. It's a striking fusion of Gotham's guardian and the age of chivalry, brought to life by the creative team of Bob Layton and Dick Giordano. If you've ever wondered what the Round Table would look like with a cape and cowl at it, this is exactly the place to start.
