.... reproduced from color slide.....
Those would be Kodachrome transparencies, the only "film" that had any sort of keeping properties. The Ansco and Agfa... not up to the task. Ektachrome didn't come around until 1942-3ish, for the war effort, to allow processing in the field, and its color-fast properties were terrible (back then).
Here's to Kodachrome, in large sheets and rolls, and in small rolls too. Alas, no more, gone, but never forgotten.
Folks, you just dont get color or detail like that from digital.... not yet anyway.
