Here is an unusual and curious version of the Lehmann “Mensa” table top delivery van. It appears to have never had a driver, nor has it had the rod underneath that keeps the car from falling off table tops, the main advertised feature of the normal Mensa toy known as EPL 688. And it sports a unique and colorful lithoed color scheme. A small number of these have surfaced, and they remain a mystery. The Mensa toy went through multiple patents over a period of years to get it to stay on the table top. Could these have been produced as a cheaper version without that feature during the interim while the company perfected the “stay on the table” model? We will probably never know.
