Bonnie Allen was another African American participant in the 1968 Miss America Protest. She is interviewed in this New York Times coverage of the event on September 8, 1968. You can see her acting in the protesters' "guerilla theater" that day, with Peggy Dobbins as the auctioneer. Here it is at a link to a short clip from the 1968 Newsreel film "Up Against the Wall, Miss America".

The coverage was nationwide:

Louisville, Kentucky Courier-Journal & Times, Sept. 8, 1968.

Stirred by the spirit of the times, it turned out that two historic protests of the Miss America Pageant were held that day, independently of each other. The one organized by the "Women's Liberation Movement" challenged all beauty contests; the other, the Miss Black America Pageant, laser-targeted the official Pageant's white racism and showcased the beauty of black women.

Below is how Life Magazine covered both protests and the Pageant itself in its issue of September 20, 1968:

A facsimile copy of Carol's paper, as it was first distributed on November 27, 1968 at a national women's liberation conference, is available on the Redstockings website in the packet called Redstockings First Literature List.
