The Faberge show at the museum was the big draw requiring a reservation and a paid ticket, but this free exhibit tucked in a back hall was just as interesting. Here's part of the description from the museum website:
"Tristin Lowe’s colossal sculpture Mocha Dick is a fifty-two-feet-long recreation of the real-life albino sperm whale that terrorized early 19th-century whaling vessels near Mocha Island in the South Pacific. Mocha Dick, described in appearance as “white as wool,” engaged in battle with numerous whaling expeditions and inspired Herman Melville’s epic Moby-Dick (1851). Lowe worked with the Fabric Workshop and Museum in Philadelphia to make the sculpture: a large-scale vinyl inflatable understructure sheathed in white industrial felt."
