Merrie Melodies - A Wild Hare (First Bugs Episode)
3:42ish going around tree
Nice silhouette use near beginning
Aw these are awesome, the backgrounds have nice textures and the fur on the coyote looks wicked. Could be a great inspiration for cartoony styling.
I couldn't find much useful stuff on Youtube but I've ordered a Looney Tunes DVD, hopefully I will find a bit more on there and post it afterwards.
