----------------------------Original message---------------------------- Peter, Two good sources for info on pictorial maps including some city maps of the type which you mention are: Holmes, Nigel Pictorial Maps:History, Design, Ideas, Sources. New York: Watson-Guptill Publications, 1991. Southworth, Michael and Susan Maps A Visual Survey and Design Guide. Boston:Little Brown, 1982. If your local library doesn't own they could probably get these through an interlibrary loan for you. Hope you enjoy them. Maureen Farrell Map Collection, Cleveland Public Library
