Cass’ dress (circa 1967) from the Rock and Roll Hall of Fame Museum’s ”Women Who Rock” exhibit.

Someone posted on the CassElliot.com forum (which even though it’s not that active lately, it still has a LOT of Cass and M&P information if anybody is interested) that they have another dress and some sheet music on display as well.

Here’s the link to the photos of some of the items in the exhibit (Grace Slick, Ruth Brown, Madonna, The Runaways, Mary Wilson, Wanda Jackson, Queen Latifah etc.)
