Anyone know history?

Found with box of glass negatives.........DuPont, maybe?

[Jim Noel]

Why do you think DuPont? They did make film before and during WWII, but I don't remember them ever being involved with cyanotype.
This information sheet is obviously for cyanotype and very likely not associated with the glass plates at all. The directions are almost exactly as I gave my students learning this part of the craft.

Azuro was sold for contact printing off glass plates, usually to make cheap postcards, as you only needed sunlight and water - no chemicals. It appears to have been sold by Sears, Roebuck & Co who sold dry plates under the Roebuck brand name.

Thank you Ian for the most informative post!

Others might enjoy the work of Henry Peter Bosse. Seeing his work on a wall is rather enlightening in this particular gallery because one of his photos was taken from a location one can see through the gallery window.

Thank You, Ian
Interesting info.........The Glass negatives that I found this with are from 1886-1896. Would not be too far out of realm of somebody getting ready to print the treasure trove of images.
Thanks again!
