42nd Street  Window Card Poster.
Carpenter Center sticker at the bottom of card.

An original window card lobby poster on cardstock and measures 22" x 14" 
Some light wear usually at the corners, review pictures to determine condition.
I have others from the same lot . These seem like they were used at the Mosque and Carpenter Center in Richmond, VA. The years in the lot range from 1970s, 1980s and early 1990s.
