Today’s is a mystery date poster.
Design by Blanche L Anish, this copy held in the US’ Library of Congress. There’s a stamp on the back, ‘July 7 1937’, so the library is dating the image to the thirties, but many details say it’s a much earlier one to me – though civil, rather than military, with an ‘Airport Worker’ listed as a career. (Details – a biplane rigger and a fixed pitch wooden propeller would’ve been very anachronistic in a very current technology sensitive industry.)
Other posters listed by Blanche (link) relate in theme, and all seem to be dated 1936-38, though no other useful biographical detail or wider works seem to be easily found. The poster is used in the book ‘On the Ground: Labor Struggle in the American Airline Industry’, though not date contextualised. The text at the bottom left reads ‘Federal Art Project WPA in Ohio’, but provides no date. Maybe a reader can add more?
