Museum worker Brittany Janaszak cleans a pectoral fin, or flipper, of a 94-foot-long blue whale model at the American Museum of Natural History in Manhattan, New York July 8, 2014. Installed in 1969, the 21,000 pound life-size blue whale model made of fiberglass and polyurethane, is based on a female blue whale found in 1925, a museum press release said.
