Saul Berman created three post office murals: Thompsonville, Connecticut (Enfield, Connecticut), The Railroad Comes to Town (Ashland, Massachusetts), and Monongahela River (California, Pennsylvania). In case you are wondering, Enfield was once named Thompsonville and there really is a borough in Pennsylvania called California.
You can see at study for The Railroads Come to Town (or The Railroads Came to Town — take your pick) at the Smithsonian American Art Museum’s website. You can also see one of Berman’s works — one that reminds us of simpler times when people went to the pictures and watched people kiss — at The MET’s website.
I’m not going to tell you what work inspired the COVID Card. You’ll know it if you see it. It is not on any of the pages referenced above. Happy hunting!
