It's by Dorothy Kent, a respected artist (mentioned in this article), who was the sister of well-known artist Rockwell Kent. Dorothy knew my grandparents and gave them this drawing when they got married. It's of a small church near Espanola, New Mexico (where my grandparents lived). I'll see if I can get a better picture and the rest of the details on the church.
I just love this picture, with its of surrealistic sense of stark simplicity. It might look plain, even a little cartoony, but has an amazing amount of depth and character to it. It now hangs in a place of pride near the front door where I can see it every day. Thank you, Nana.
