1946 1947 1948 PLYMOUTH newspaper advertising art

Description

original 1946 1947 1948 PLYMOUTH
advertising mats
used for local newspaper advertising
6-5/8" X  7"
each individual car is 1- 3/4" wide
this is one sheet with 13 different models
I'm not sure what the process was to take these and make a newspaper ad., this style is called "mats", these same designs were also made on metal, mounted on wood like printers blocks.
these mats are super rare 75 years after they were used
I have some 1948 Chevrolet truck mats listed, and will be listing some other automobile related mats
