Years in Production
Millerton Dairy Farms of Mankato, Minnesota was one of the largest producers of milk, cheese, and other dairy products in the Minnesota area.
Millerton, as part of a promotion related to chocolate milk, issued a set of baseball cards in 1966.
These cards were glued to cartons of chocolate milk, making examples without glue stains (or moisture and handling issues) quite scarce today.
Millerton cards are highly collectible today due to an unusually wide selection of players for a small and limited issue.
