Strauss, Allard & Meyer
Strauss, Allard & Meyer were Paris-based makers of necessaires and other small boxes and accessories of the 1920s and 30s. They took out patents on some of their specialized mechanisms, even in the US to protect against copying. They supplied Cartier, Van Cleef & Arpels, and Lacloche among major high-end retailers.
There aren't any objects involving Strauss, Allard & Meyer that have been photographed yet or maybe they have (had their pictures taken) but we can't show them to you right now.
