Hopper was no doubt influenced by them.
I am also very fond of 20th century self taught artists. They paint for the love of it without a thing to prove to anyone.
Counter that with the laugh out loud foolishness of many contemporary artists.
“If you have a chance ( and forgive me if you know about them ) take a look at the Ashcan School ”
This is astonishing. I never heard of The Ashcan School until 2 days ago. It was a crossword puzzle clue-— (Sloan was the answer). I then read about them and was fascinated.
I’m early 20th century too-—born in 1932. :-)
