Jeepster paper collectors (literature, ads, etc) might be interested in knowing that In 1948, Willys-Overland send out an unknown quantity of their large showroom brochures that were "defective". I have a regular version and one of the defectives with the Newark NJ distributor's retail showroom stamp on it. The defect is obivious. The back cover of the item has condensed specifications; the defective one has a blank back cover.
Or maybe the one I have is a one-off that didn't get printed during the run? There is a Kaiser-Frazer SALESPROMOTER that didn't have the red ink on it that I have a copy of.
