You're probably familiar with Milton Glaser's work, even if you don't know it. The graphic artist is the man responsible for creating the ubiquitous 'I love NY' logo that adorns T-shirts, coffee cups, bags and caps across the world.



Glaser created the logo in 1976, when New York wasn't the tourist haven it is today. "The place itself had become so difficult to live in," he told the Guardian's Ana Terra Athayde.

"I wanted to say 'I'm gonna stay, I love this place, I'm not gonna be defeated, I'm going to make it better'."



Now 85, Glaser runs a studio in Manhattan and has a body of work – which includes Brooklyn Brewery logo and a poster for Bob Dylan's greatest hits album – that has made him a legend in his field.



His latest project is his most ambitious yet – in collaboration with New York's School of Visual Arts, he has launched the campaign 'It's not warming, it's dying', in a bid to raise awareness of climate change.
