Many years ago I used to work as a Photoengraver / Blockmaker, letterpress printing industry.
This would have been made in a Photoengraving Shop for a period advert. for a 1932 Ford. It would have been commissioned by Ford Advertising, not made by Ford!
It would have started as a hand done line drawing by an advertising artist. Then at the Engravers, it was photographed & sized to negative film [ reversed image, so it prints opposite] ; exposed onto zinc plate which had been coated with a light sensitive solution; then treated in chemicals & washed off with only the exposed areas remaining as the line image.
The zinc plate with image then is rotated in an etching machine containing a solution of Nitric acid, oil & water which over an ascertained time eats down the metal except for the exposed image which is acid resistant. The resulting relief image is cleaned & finished & finally mounted on a block of wood so it can be placed in a form with type to be at the correct height for printing on a letterpress printing machine.
This all involved a lot of hand work by skilled tradesmen, as you can imagine.
This would be a rare item which I wish I had. They would be either worn out if used for a long run, or damaged or usually just discarded after a few years storage.
Hope I have not bored anyone with all of this.
