There is no date on this Cochran Artnamel salesman sample, but one source indicates 1930s, more or less. Hmm. A shame, as this seemingly defunct brand had a good name. Artnamel! I like it. I would use a product called Artnamel to paint my little models(if I had any) and what-have-you(s?) and I used a trademark search to see if it is available. It is! My scan was brief and I am no lawyer, but it seems to be another trade name in the graveyard of color.
