“Sunday morning elevated, 1925.”
Based on a 1942 record-picture photo of the New York elevated railway platforms, made for the U.S. Office of War Information. HPL added by me. So far as I’m aware, the source picture’s U.S. government status should put it into the public domain, and thus I’m open to offers to use this version as a book cover. Space could be added above/below for titles etc. The painting can be polished up a bit if needed.
