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 listed. 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.
