Yes, the Charlie Chan cartoons are available from a number of sellers, and I believe that I have seen "Charlie Chan and the Amazing Chan Clan" for sale on eBay. That series is interesting to Chan fans because Keye Luke, who played Charlie Chan's Number One Son, Lee, in the film series, provided the voice for Charlie Chan in the cartoon series.
If you go to your favorite search engine and type in "Charlie Chan and the Amazing Chan Clan," you will doubtless find something. Good luck in your search, as half of the fun lies in that very search!
