Cardboard Heroes are full-color, standup cardboard figures in 25mm scale for a fraction of the price (and the weight!) of metal miniatures.
Originally supplied as packs of individual cardboard sheets with 15mm scale figures, then with other Steve Jackson Games products (e.g. Floor Plan 1: Haunted House), they were then published again as a product of their own as spiral-bound cardboard pages. Newer products in the line are available as PDF downloads.
