The late Keith Haring's pop imagery, like his pal Andy Warhol, lives on everywhere from shoes to iPhone cases to museum walls. In 1984, Haring visited Melbourne, Australia and painted a mural in the Collingwood neighborhood as a present to the city. Haring's mural has suffered wear and tear over the past 1/4 of a century, so a group has formed to help restore the work of art. To help save Haring's Melbourne mural, go here  and sign a petition.
