Ingrid Ann Thompson, left, and Deborah Jane Wilcox, both of South Portland, give each other a taste of the two kinds of cookies sold by local Girl Scouts in a photo from 1956. The girls, both eight, were members of Brownie Troop 127 and proceeds from the sale went toward a new infirmary at Camp Cedar Cove in Litchfield and a play field and new camping equipment for the day camp in Scarborough.
