HT to Orange Crate Art.
Edward Caswell’s illustration of a willow tree, shown above, served as illustration for one of my favorite books about the city: Here is New York (1949). Caswell’s sketches of New York appeared in numerous periodicals throughout the 1940s and 1950s before he passed away in 1963. This tree was still standing in 2002.
As Professor Leddy notes, there are a few Edward Caswell illustrations available for sale at Deep Archives.
