The Knave of Hearts

One of the numerous Defenders for a Day was Jack of Hearts—real name Jack Hart. Because of his motif, I tend to associate that character with the Knave of Hearts, who was accused of stealing tarts in Alice in Wonderland.

Around the time he sought membership in the Defenders, Jack of Hearts starred in Marvel Premiere #44 (Oct. 1978); the Knave of Hearts and other Wonderland characters featured prominently on the back cover of Marvel Classics Comics #35.
