This terrific image of dogs reading, writing and attending school is by the well known vintage pets artist, Louis Wain. Known primariiy for his anthropomorphic images of cats, Louis Wain also made a large number of dog images, mainly in his earlier years. He illustrated about one hundred children's books, and his work appeared in papers, journals, magazines. He also created a large number of greeting cards and postcards featuring dogs and cats in human situations. This image is from a 1910 postcard which I've restored to the best of my ability.
Melanie, I love all these pet images you have here. You have a great selection! As a person who has had a pet of one kind or another all her life, this is a great store! But mostly I've had cats. We used to have an American Eskimo dog that we rescued from the shelter. They are great family dogs.
