Blossom by Polly Apfelbaum, 2000, MoMA, NYC.
This piece is part of a series of installations Apfelbaum did that were named for, and dedicated to The Powerpuff Girls characters from the animated series. Apfelbaum liked the juxtaposition of the young girl characters possessed of super powers and fighting for good. The artist created each "petal" separately and then installed them piece by piece.
