Uncanny X-Men #98 Splash Page (April 1976)

The splash page to Uncanny X-Men #98 is one of the most heartwarming holiday vignettes in the long history of Marvel Comics. The scene features the whole team in their civilian clothes taking much-needed time off to enjoy the season by the Christmas Tree and Skating Rink at Rockefeller Center. This splash page is also a veritable treasure trove of cameo appearances and Easter Eggs. In addition to the X-Men and Moira MacTaggert, the foreground features the first appearance of Amanda Sefton and her friend Betsy Wilfred, Daredevil Matt Murdock, Nick Fury with La Contessa Valentina Allegra de Fontaine, and X-Men artist Dave Cockrum with his first wife Andrea Kline. As if that wasn't enough, you can see Doctor Doom skating along at the north end of the rink. Pure genius by Cockrum!
