The Smithsonian’s collection of sketches on cards and letters is captivating, including this perfect example.  Well known illustrator Warren Chappell created the postcard to send to fellow artist Isabel Bishop in 1982, writing:

I’ve just thrown a couple of drawings away and I realize—there’s no friend like a trash basket.

The friendship between these artists resulted in numerous sketches, including this one below, also to Isabel Bishop, and also from the Smithsonian’s Archives of American Art.  Chappell placed the quote by Ralph Waldo Emerson, in red, beneath the tree, to illustrate the process of aging:  “A painter told me that nobody could draw a tree without in some sort becoming a tree.”
