Collection of over 500 altered-image postcards showing cities and towns "in the future". Photographs are modified to include blimps, airplanes, balloons, monorail systems, and other kinds of transportation devices. Other categories of the fantasy postcards include images of "rippling buildings" and postcards depicting the end of the world (a response to the panic of the 1910 appearance of Haley's Comet). A flash drive with an inventory of the collection and images of the fronts of postcards is included. Filed with these are an additional 85 postcards about or featuring postcards.
