Postcard, St. Bernard Puppies by a Pond, 1909

Depictions of dogs and puppies often appeared in art and folk art in the United States. Inexpensive lithograph prints made in the mid-19th century emphasized people's relationship with dogs. Starting in the late 1890s picture postcards included these types of popular illustrations of dogs. Sending colorful postcards through the U.S. mail continued to be widespread well into the 1910s.
