Card 140 was inspired by post office muralists Harry Louis Freund and Richard Sargent.
Freund painted four post office murals: Early Days and the First Post Office in Pocahontas (Pocahontas, Arkansas), Arrival of First Train in Herington – 1885 (Herington, Kansas), Agriculture and Varied Institutes (Windsor, Missouri), and The Last Home of the Choctaw Nations (Idabel, Oklahoma). My favorite Freund work is the etching, Pot Belly Stove.
Richard Sargent was much better known for his Saturday Evening Post covers, however, he did create one post office mural: Men at Rest (Morrilton, Arkansas). I like his gritty industrial scenes seen here and here.
