I had only seen the right part of his painted ad on 8th Avenue near West 47th Street, advertising rooms with steam heat, hot and cold water, and housekeeping.
The rest of the wall has become recently visible, and there is what seems to be an ad for “Society Smokes” and one for shoes at the upper right.
This reminds me of an ad for Young & Schmuck Billiard Parlor that was briefly uncovered a couple of blocks away in 2001 before its building was demolished.
I estimate both ads go back to the 1890-1910 period.
Thank ForgottenFan Jim O’Neill for this find.
