Glaser was responsible for the design of many other publications. Over the course of his long career, his creations have tended to change from hard-edged Pop and psychadelic designs to a softer, more expressionistic or naturalistic style. Glaser's work includes the creation of many ''posters'', notably the iconic Bob Dylan silhouette (1966); book and record covers; book illustrations; type; corporate logos; interiors; and architectural projects. One of his most famous designs is the 1976 "I Love New York" logo.
Glaser has put his visual stamp on many other pieces of late-twentieth-century life, including buildings, consumer goods, advertising campaigns, and numerous publications. He has also illustrated several children's books, including two by his wife, Shirley Glaser.
