[Authors: Cliff and Linda Hoyt's collection started with the seemingly harmless discovery, in the 60's, of an old E.W. Hoyt's Rubifoam bottle on Colorado's Pikes Peak. In the early 1970's, they began concentrating on trade cards since good bottles were too expensive. Of course trade cards led to bigger and better things. The Hoyts expanded their collecting to include bottles and advertising from the Lowell Mass. companies of C.I. Hood (medicines), J.C. Ayer (medicines), and E.W. Hoyt (cologne and Rubifoam for the Teeth) starting in 1973. In addition, they collect theatrical memorabilia from playwright Charles Hoyt from the period 1885-1901.
