If nothing else, the Walter Lantz cartoons of the late ‘50s had the nice work of Ray Jacobs and Art Landy. I don’t know whether one did layouts and the other backgrounds or if they switched off.
Here’s one of their pieces from “Everglade Raid” (1958), the first cartoon when Woody Woodpecker takes on an alligator that sounds like a slightly-enthusiastic Huckleberry Hound.
Landy had been a background artist at Disney. His last theatrical credit was on Lantz’s “Window Pains” (1967). Jacobs left Lantz around 1960 to work for Jack Kinney, then drew layouts for Filmation and Hanna-Barbera.
