The LOVE image was originally designed as a Christmas card for the Museum of Modern Art in 1964 and first exhibited as a sculpture in New York City in 1970. The original sculpture has been on display at the Indianapolis Museum of Art since 1975:
The sculpture has since been reproduced many times and in many forms. The sculptures can now be found all over the country (not to mention in jewelry, postcards, T shirts, and so on). Here it is in LOVE Park in Philadelphia:
And on the campus of Wichita State University:
Back in New York City:
And up in Rockland, Maine:
It's even on display in Hebrew at the Israel Museum.
At the risk of taking the words of my all-time favorite TV show in vain, "love really is all around!"
