The largest flower auction in the world is in Aalsmeer. There’s an interesting video clip of it here.
“Famille attablée sur la terrasse, ombragée par une bâche,” (family at a table on a terrace, shaded by a tarp) ca. 1890 – ca. 1910, by Eugène Trutat*, via Bibliothèque de Toulouse (cropped slightly by me).
*I was skeptical about the photographer because Trutat died in 1910, and the women on the left appear to be in the shorter dresses of the 1920s or 30s. However, they could be wearing the bathing suits of around 1900.
“Människor som sitter i en trädgård” (people sitting in a garden), Lysekil, Sweden, ca. 1890, a cyanotype by Carl Curman, via Swedish National Heritage Board Commons on flickr.
Carl Curman was a physician, specializing in the science of health baths (balneology). He also became a prominent amateur photographer, leaving behind a collection of about 700 photos. He lived with his wife, Calla (possibly the first person on the left above), and their children in Stockholm and, during the summers, in the seaside town of Lyskil.
The group above may be in an outdoor cafe of the park in Lyskil, rather than in a private garden. The spot looks very much like the one in this photo by Curman.
