What was really gorgeous? Dye transfer prints from Kodachrome originals. Dye transfer seems to be another technology that's fallen by the wayside, too complicated, too time consuming, but the dyes were extremely stable.
ASA 25 Kodachrome II didn't hit the market until the early sixties. Before that Kodachrome was ASA 10, extremely contrasty, and still people complained that the new Kodachrome II was no good, not contrasty enough, softer colors, too much shadow detail...LOL
