“Semiotics is the study of signs and the messages they contain.” This is the opening sentence of a marvelous book by Jack Child entitled Miniature Messages: The Semiotics and Politics of Latin American Postage Stamps, published by Duke University Press in 2008. There have been a number of similar books written about the stamps of the United Kingdom, the Netherlands and Italy, among others. I am unaware of any such work devoted to paraphilately.
