That’s a cat at the bottom of the steps.
I have not been able to find out anything about these siblings or the home. I cannot find an Old Lodge in Terlow, Buckinghamshire, or indeed a Terlow anywhere in Great Britain. The Martineau family is quite important in Birmingham (an ancestor of the Duchess of Cambridge was a Martineau), but apparently not in Buckinghamshire. Perhaps the photographer made some mistake in his notes.
The son on the right seems to have three golf balls between his fingers. A young amateur champion?
“Crossing the painted road which extends east from The Philadelphia Museum of Art, August 1973,” by Dick Swanson, via the U.S. National Archives Commons on flickr (all photos and captions in quotes here).
Swanson took these images for DOCUMERICA, a photography program of the U.S. Environmental Protection Agency (EPA). From 1972 to 1977, it hired over 100 photographers to “document subjects of environmental concern.” They created an archive of about 80,000 images. In addition to recording damage to the nation’s landscapes, the project captured “the era’s trends, fashions, problems, and achievements,” according to the Archives, which held an exhibit of the photos, “Searching for the Seventies,” in 2013.
“The art of cooling off is enthusiastically pursued in the fountains of The Philadelphia Museum of Art.”

The pencil and watercolor drawing comes from an album of poetry and fanciful sketches of bugs and birds. It was found in the 18th century manor house of the Saadjärve estate, which has belonged to several noble Baltic German families over the centuries. The album may be connected to the von Koskulls, who owned the property in the 19th century. There are more examples of the drawings here.
By the way, an Instagram post by @smithsoniangardens reminds us that although “[t]hey may be less elegant than other pollinators, . . . beetles have been providing their pollination services far longer than many of the well-known pollinators. Ancient and abundant in numbers, there are almost four times as many species of beetles as animals with backbones!” (This is Pollinator Week.)
