Oy, now that you mention it, I have found it...
Albert Lamorisse «Le Ballon Rouge» (1956) on Vimeo
Might update it this late nite now that the hardest part (finding a streaming, clickable, playable version) has thus been conquered.
Next in my queue after sharing is:
a Chaplin featurette (if I can find one)
a Lloyd short (also, if I am fortunate)
a Laurel and Hardy short comedy (dig one up)
I don't know why it is so hard to maintain my Cartoon thread, but until I become a moderator, which I fear is never going to happen, I might as well just stop trying to meticulously curate my themes, because no one else cares much about them, and without a sovereign hand over what is being contributed, I'm left to feel like schlemiel when I ask for the tiniest things in order to ensure contuinity and expectant quality.
