Paris: Ch.Chardin, undated, 1930s. Pamphlet. 8p., numerous b&w photos/artists' renderings of electrical devices (stored neatly or in use), a few patients photographed or sketched, semi-glazed alkaline paperstock. No merely manual techniques are shown (compiler recommends a book for that), instead, everything shown is electically enhanced: "air chaud et froid, vibro-masseurs w/accessories, manu-vibrateur, massage electrique de haute frequence, maigro-masseur, massage faradique ou d'induction (par piles), table de massage".. there is text besides the lengthy captionings. Condition: pretty good, pace a bit of edgewear, dust-soil and corner-tip creasing externally, and crimpings throughout the ads. Sound enough, and unmarked except for an old dealership code in pencil. Let's describe it as "good", meaning "good only"
Our dating is based on the lot it turned up in, and the fact that the cover design looks "art deco" - though the various machines look prehistoric. It could well be that M. Couvert reissued the same catalogue over time, just changing its appearance.
