I heart NY design 'almost never happened'

The iconic I Love New York design almost never came into existence, says its creator Milton Glaser.

He was working for an advertising agency on the commission and had submitted an approved design for the project but while he was travelling in a New York taxi he realised he had a better idea.

"It almost never came into existence. The interesting thing about it is that this persistent visual mark could have vanished overnight and like most things never been seen again."
