Carte-de-visite, Boy with dog, ca. 1868

Here's a carte-de-visite showing a young boy named Eugene in an off-the-shoulder dress. the diagonal rug pattern mimics the bias-cut diagonal plaid of his dress. I'm thinking late 1860s for this one, based on the clothing and the style of the CDV.

Cabinet Card, Boys with Goldfish, ca. 1908

It's possible that the fishbowl is the photographer's prop, but it was not unusual for families to bring pets to the photographer's studio, including bowls of fish and songbirds in cages. These well-to-do-boys have bowl haircuts stylish in the late 1910s, with their heads shaved below the bowl. They are wearing kid shoes — Mary Janes on the older boy and shoes with ankle straps on the younger brother.
