Pinback buttons from my collection

All types of pinback buttons and other celluloid advertising items interest me. I particularly like early items (1869 to 1920) that are graphic and historically interesting. I also like political campaign buttons and related memorabilia. Most of the items I collect are celluloid and range from 3/4 inches in diameter to 9 inches. I am particularly interested in early advertising, street fairs, Worlds Fairs, sports, comics, vaudeville, aviation, automobiles, famous people, woman suffrage, prohibition, Lindbergh, United Confederate Veteran reunion items, and so on.
