Originally drawn and rendered in-house by DC Comics,
Gotham's Dynamic Duo is created in the style used for the
first season Warner Bros. Batman animated series.
This series inspired an entirely new style of animation
called "Dark Deco," where by the backgrounds were painted on
black paper, giving Gotham an entirely new personae and
darkness which melded with Batman's character.
This also was the first Batman series to concentrate
heavily on the personalities of the character, making it as
much a character-based theme as it was based in action.
Robin in this series was Dick Grayson, who was
redesigned to appear more hipper and adult-like. This Robin
is not to be confused with the Robin in The Adventures of
Batman and Robin and Teen Titans, who was Tim Drake, and
much younger.
Each of "Gotham's Dynamic Duo" has been hand-numbered
and signed by Bruce Timm, Alan Burnett and Paul Dini.
