Push Pin Graphic, no. 21

1017
"Started by Push Pin Studios as a freeform publication sent to friends and clients in 1957, the experimental and groundbreaking Push Pin Graphic, quickly developed a dedicated following, eventually running for 23 years and 86 issues. Changing to a 32-page bimonthly in 1976, and continuing publication until 1980, a limited number of copies from this latter period are still available."—http://www.pushpininc.com/gallery/pushpin-graphic/#hereos
