Where is the Original LOVE sculpture?

I was reading a page about Philadelphia tourism, and it said the LOVE sculpture in Love Park is the original sculpture by Robert Indiana (it was first a painting and stamp). It has now been made as replicas in places such as NYC, Singapore, and Taipei. I was under the impression that the original is at the Indianapolis Museum of Art and was built in 1970. I think the Philly version was installed in 1976. Thoughts?
