Push Pin Studios

After graduating from Cooper Union, Sorel and Chwast worked for a short time at Esquire magazine, both being fired on the same day. Joining forces to form an art studio, they called it "Push Pin" after a mailing piece, The Push Pin Almanack, which they self-published during their time at Esquire. Sorel and Chwast used their unemployment checks to rent a cold-water flat on East 17th Street in Manhattan. A few months later, Glaser returned from a Fulbright Fellowship year in Italy and joined the studio.

Sorel left Push Pin in 1956, the same day the studio moved into a much nicer space on East 57th Street. For twenty years Glaser and Chwast directed Push Pin, along with graphic designers and illustrators such as John Alcorn (in the late 1950s), Paul Davis (1959–1963), Barry Zaid (1969–1975), Paul Degen (1970s) among others. Today, Chwast is principal of The Pushpin Group, Inc.

Over the last six decades, the firm's work, and that of the founding designers, along with Reynold Ruffins, Edward Sorel and several other designers who have been associated with it, has led to several books, as well as publication in The New York Times, The New Yorker, The Wall Street Journal, Vanity Fair, The Atlantic, and Print (magazine) and traveling exhibitions, such as "The Push Pin Style," which traveled to the Museum of Decorative Arts of the Louvre, as well as numerous cities in Europe, Brazil, and Japan in 1970–72.
