In the early sixties there was a new (but not overly loved) Disney character by the name of Ludwig Von Drake ...
Drake showed up in the Fall of 1961 to introduce color to Walt's revamped anthology show, then moving from ABC to NBC.
Drake continued showing up for some years thereafter, and I, a kid at the time, always found him irritating. (Maybe it was Paul Frees' fake German accent, maybe it was Von Drake's frenetic personality. But whatever the underlying issue, I found the fowl forced and unfunny.)
L.V.D. had a short-lived comic book (four issues), and he's appeared sporadically in various animated products throughout the years. Mega Collector -- who own the drawing up top -- doesn't know who did the thumbnail board, but speculates it was done early in Von Drake's professional life, probably '61 or '62. (By Ward Kimball? Ward once told me he animated Von Drake at a breakneck pace, drawing him small on the hole-punched paper so he wouldn't waste a lot of pecnil mileage on him.)
But I can understand why Mr. Kimball would work on L.V.D. has quickly as possible. The bird is something of a pain in the backside.
