Photograph of a dog staring at a pigeon (occupational portrait of a hunting dog, cabinet card photograph)Late 19th early 20th century cabinet card photograph, 4 x 5. 5 inches, mounted to 4. 25 x 6. 5 card. Pencil inscription on the reverse reads, "This is supposed to be President McKinley's dog." McKinley was in office from 1897 until his assassination in 1901; he isn't recorded to have a dog as a White House pet, but this looks like a hunting dog. Posed opposite a pigeon fowl on a tablecloth, the canine version of an occupational portrait?
