Following on the discovery of 14 Alice Comedies possessed by the EYE Film Archives by rbudrick, I inquired what other American animated titles they possessed. I was given access to stream the following, all apparently stemming from HD transfers of Dutch-retitled (35mm?) prints:

OUT OF THE INKWELL
Surprise
Chemical Koko (?)
Koko's Focus

FELIX THE CAT
Arabiantics

AESOP'S FABLES
Hanuted Ship
Circus Capers
Singing Saps
Prova d'orchestra (appears to be Noah Knew His Ark)

Did a quick skim through the very compressed full-length preview videos and the Aesop's Fables are all sound-era and presented in a slightly narrower ratio.

I also inquired whether they had any of George Pal's early European Puppetoon commercials and was sent quite a handful to stream as well, all from PAL SD masters:

De Tooveratlas
What Ho She Bumps
Aethersymphonie
Radio Value Revolution (cel-animated)
The Philips Broadcast 1938
Charlie's World Cruise (cel-animated)
In Lamp Light Land
Het Aetherschip
Doornroosje
Philips Calavade
South Sea Sweethearts
Sky Parade
On Parade
Ballet of Red Radiovalves
Hoe Een Reclame-Affiche Ontstond (live action/cel-animated)
Aladdin en de wonderlamp
De Reddingbrigade
