Kobutori (1929)

Both are one of the first anime ever created that still exist today, and if you liked one of them you will certainly like another. Kobu-tori is a folktale, while Komori has special "old cartoon" appeal while telling fable like story with animals. Both are good for "expanding the horizons", bragging that you watched an anime made before they were "mainstream" and for casual enjoyment.
