The cause of death was a stroke, his wife of more than 50 years, Shirley, told The New York Times.
While his local claim to fame was the graphically catchy, and emoji-prescient, New York logo — imparting the message “I Love New York” using just three letters and a heart — the Bronx native was a prolific designer.
His noteworthy designs include a psychedelic, 1967 poster of Bob Dylan.
Glaser only closed up shop on his Kips Bay offices — a 10,000 square-foot Beaux-Arts townhouse where he helped found New York Magazine — in April of last year.
“Art is Work” was etched on the glass transom over its front door, The Post noted at the time.
In later years, he and Shirley split their time between Manhattan and Woodstock.
“At this point in our lives, we do virtually nothing,” he told The Post in 2017.
“We have a beautiful house in Woodstock [NY]. It’s the alternation of those experiences that matter.
“After we’ve been in Woodstock a week or two, we think of NYC as a vacation. The ability to choose your energy level and environment, and feeling you have that choice, makes it delightful.
“At a certain point, you find you want to spend most of your time alone — in this case, with your wife — doing modest things and not going more than six or eight blocks from where you live.”
