16 small metal trays, print calico farm animals cow, hen, pig, duck

Bright calico farm animal litho print metal trays, marked Taiwan, early 80s? This is a nice big collection, sixteen trays in all (four each of cows, pigs, chickens and ducks, about 7 1/2" long).

One of the duck print trays is very faded (it's been stored on the top of the stack of these trays for about 30 years!). A couple of the other trays have some light rust spotting or scratching, but most look very good.
