Robert Lepper was an artist, designer, and educator. As an educator, he is said to have encouraged his students to look at every day objects as potential works of art. One of his students, Andy Warhol, excelled at not only looking at every day objects as potential works art, but making them into works of art.
While a few major museums, like the MoMA and the Whitney, are said to have some of Lepper’s works, the only museum I could find that displays his work on its website is Carnegie Museum of Art,
Lepper created two post office murals: The Lumber Camp (Grayling, Michigan) and Noble County-Ohio (Caldwell, Ohio).
