Every year the San Diego Comic-Con puts together a souvenir book that spotlights various anniversaries, such as the 50th anniversary of Green Lantern or 25th anniversary of the Teenage Mutant Ninja Turtles. The book features artwork from professionals and fans celebrating these anniversaries.

Well, this year is the 25th anniversary of Stan Sakai's Usagi Yojimbo, and he's posted artwork by none other than Stan Lee featuring everyone's favorite ronin rabbit wearing everyone's favorite webslinger's mask. "Other contributors include Sergio Aragones, Dan Spiegle, Dean Yeagle, Kazu Kibiushi, Bill Morrison, Mell Lazarus (Mama as Usagi), and Scott Shaw!" Sakai said on his blog.
