The original art was not a sculpture at all, but a simply-styled piece of 1960s pop art from creator Robert Indiana.
Indiana originally designed the image as a Christmas card for the Museum of Modern Art in 1965, more than a decade before it went to Philly. Since then, it has appeared on stamps, banners, rings and sculptures around the world.
For years, the love sculpture in Philadelphia was accented in blue and green, a departure from its original hues.
This year it has been returned to its original color scheme: red, green and purple.
This isn't the first time the sculpture's been taken down in Philadelphia.
It was briefly removed in 1978 before the city decided it should have a permanent spot in its park, and then lifted away again here in 1999, for restoration.
Deborah Wye, retired chief curator of prints at the Museum of Modern Art, says the image is "full of erotic, religious, autobiographical, and political underpinnings."
Wye argues the sign often served as an "emblem of 1960s idealism," an iconic reminder of free love.
There's another copy of the statue in New York, and translated versions of the sculpture around the world, including one in Hebrew in Jerusalem.
Whatever your feelings about Valentine's Day may be, one thing's for sure: There's just a little more LOVE out on display today.
