The pictureshows two views of the (2) 1968 Post Cereal Prize Mercury Scale Model Cars in this lot. These toy cars were prizes in boxes of Post Honeycomb cereal (and maybe others) in 1968. They are made of light blue and blue color plastic with black wheels. They are marked on the bottom as follows:
(Mercury Marquis) JVZ CO 2
(Mercury Cyclone CJ) JVZ CO 11
The cars each measure about 3-3/16'' long. They appear to be in near mint to mint condition as pictured.
