Vintage Swap Trading Cards Featuring Dogs

These beautiful 1940's - 1950's vintage swap trading cards feature a dog picture on one side, and they are blank on the back.  As a fan of both ephemera and vintage dog items, I really enjoyed scanning, researching, and listing these cards.

This especially nice card features a Gladys Emerson Cook illustration of a blonde cocker spaniel and a tabby cat in front of a door marked "Quiet Please":
