Tex Avery - The Three Little Pups

Here's some layouts and model sheets from "Three Little Pups". This cartoon marks the first appearance of the southern accented wolf voiced by Daws Butler. There's also some great backgrounds in this cartoon by Vera Ohman, who would later paint backgrounds at Hanna-Barbera under her married name Vera Hanson. (Thanks to John K. for informing me of this.)
