Bearing a Resemblance

While looking through back issues in my collection, I noticed that the covers of Avengers #169 (March 1977) and Uncanny X-Men #139 (November 1980) bear a resemblance to one another. Each cover shows members of the respective teams facing three threats—with a polar bear in the upper right of both covers. In all transparency, the polar bear on the X-Men cover is actually the shapeshifting hero Snowbird of Alpha Flight.

In addition to defeating an actual polar bear in the Arctic Circle, Black Panther impresses his fellow Avengers by providing the final answer on a challenging crossword puzzle. A twelve-letter word that means "producing sweat"? Sudoriferous!
