As I was wandering through the Lost Barrio (a commercial area on a dead-end part of Park Avenue south of Broadway) on August 22, 2018, I spotted this little mural on a wall by the entrance to Tooley's Cafe. It seemed to have been painted around with new wall paint, as if it had been there for a while.
The caption was a bit faded out; I darkened it. It says “Painted for Patricia / In the year Two Thousand Ten / Francisco”
