Here is a pair of Turner Dairy Advertising Cows.  They are both brown and white painted plastic.  Both are stamped on the base - one is stamped darker than the other.  Both have some flecks of paint missing but nothing too serious and no scratches.  Flecks missing only look like additional patches on the cows.  Rare find.  Measures 2 1/2" long and 1 3/4" tall.
