This cel features Mighty Mouse and Bat-Bat from the 1987-89 revival by Ralph Bakshi. Many other very talented animators worked on this series including John Kricfalusi and Bruce Timm.
Wkikpedia has a great history of the series which can be found here : http://en.wikipedia.org/wiki/Mighty_Mouse:_The_New_Adventures
Excerpt from Wikipedia:
The show was considered revolutionary at the time, and, along with 1988's Who Framed Roger Rabbit, inspired a wave of animated shows that were much zanier[2] than those that had dominated children's animation in the previous two decades. It is credited by some as the impetus for the ‘creator-driven’ animation revolution of the 1990s.[3] It was a huge springboard for many cartoonists and animators who would later become famous, including John Kricfalusi (creator of The Ren and Stimpy Show), Bruce W. Timm (producer of Batman: The Animated Series), Jim Reardon (writer for Tiny Toon Adventures, Wall-E and director of many Simpsons episodes), Tom Minton (writer and producer for many Warner Bros. television cartoons, including Tiny Toons, Animaniacs, The Sylvester and Tweety Mysteries, Baby Looney Tunes and Duck Dodgers), Lynne Naylor (co-founder of Spümcø, character designer for Batman: The Animated Series and storyboard artist for The Powerpuff Girls and Cow and Chicken among other work), Rich Moore (animation director for The Simpsons and Futurama), Andrew Stanton (director of Finding Nemo and Wall-E) and others.[4] Kricfalusi supervised the production for the first season and directed eight of its twenty-six segments.[5] Kent Butterworth supervised the second season, after John Kricfalusi's departure to work on the similarly shortlived 1988 animated series The New Adventures of Beany and Cecil.
