The artist Peter Max, who died on Monday at the age of 88, was best known for his psychedelic posters from the 1960s, but he apparently also designed for the theater. Twice.

In 1967, he designed the poster for the Off-Broadway revival of “The Coach with the Six Insides,” at the East 74th Street Theater, Jean Erdman’s adaptation of James Joyce’s “Finnegan’s Wake,” combining dance, mime, acting, and a stream-of-consciousness script.

In 1969, he designed the program for the Winston Churchill High School production of Meredith Willson’s musical “The Music Man“, done at the height of Max’s fame as a favor after the San Antonio, Texas public high school contacted him. He used his signature character “Cosmic Runner” and put a trumpet in his hand, to suggest the musical’s main character Harold Hill.

These were the only theater posters I could find designed by Peter Max himself, but his “Cosmic Pop” style influenced the posters of many Broadway and Off-Broadway productions in the 1960’s and 1970s.

The 1968 poster for “Hair” was designed by Alexius Ruspoli-Rodriguez

The 1971 “Follies” poster was designed by David Edward Byrd,

This 1972 poster for “The Selling of the President,” which parodied Peter Max’s style, was designed by an unnamed member of the , Blaine-Thompson.agency.
