A LEGO version of Robert Indiana’s iconic "LOVE" sculpture from 1970. Best known for its regular appearance on postage stamps, the original sculpture is on permanent display in Philadelphia and copies are in many cities around the world. Built for the BayLUG "All You Build Is Love" challenge from the February 2009 meeting (which, not to brag, it won).
The original, for reference:
