This is a Busy Beaver Button Company variation of the I heart NY logo that was created in 1977 by Milton Glaser for an ad campaign created by advertising agency Wells Rich Greene. The marketing campaign was sought by then-Deputy Commissioner William S. Doyle to increase tourism in the state of New York. The campaign was a wild success. The original sketch of the logo is permanently on display at the MOMA.
The logo has become iconic in pop-culture and has been imitated in many forms around the world.
