This is part of an composition at the Museum of Contemporary Art by an artist named Kristi Lippire. In a complementary exhibit to the Calder retrospect, the MCA has artists whose work is in the same style/inspired by Calder.
This piece, really titled Three Under Parr and based on some photographs by another artist named Martin Parr, is made of found objects. Individually, each pig petit four is an art sculpture. Combined, they create a larger artistic piece.
