Gaston's Easel Life (1958)

While Gaston LeCrayon is setting up his painting area on the sidewalk, a limousine zooms by and splashes mud all over the canvas. The wealthy woman, who was a passenger in that limousine, mistakes the mud-splashed canvas for "art" and invites Gaston to her mansion, wanting him to create a masterpiece with her expensive art supplies. Her husband, however, has different ideas.

Unfortunately the movie Gaston's Easel Life is not yet available on HBO Max.
