Batman made his first ever animated series appearance in the Filmation
produced Batman/Superman Hour in 1968 and was given his own series,
The Adventures of Batman and Robin in 1969. Seven years later he
returned with all new episodes in The New Adventures of Batman. All
three animated series followed the familiar story lines of the comic
book and it ran on CBS from 1968-1970 then from 1977-1981.

The best site on the web selling Original Production cells is Sci-Fi
station which has a great selection, with prices ranging from $310 to
> $600.

You can also find the occasional cell coming up for sale at the
newsgroups alt.comics.batman and alt.animation.batman and with these
you might get the chance to haggle the price with the owner. If there
is a particular episode, of character you're looking for, these
newsgroups are the place to ask in, containing as they do die-hard
fans of the Dark Knight.

Hope you find what you're looking for
