Glass blueprint 2021 (with holder) *Exhibit

This is a blueprint of a glass made from a wet plate photograph. On the 6 cm x 9 cm glass, the blueprint (prototype) and the collodion process of [new moon 6 x 9] in 2021 are marked with illustrations. The amount of information is equivalent to about 8 sheets of A3 size paper.
In the future, when wet plate photography is discontinued, I created it so that I can reproduce wet plate photography by deciphering this glass.
 
There are some scratches on the glass because it is an exhibit, but there is no problem with viewing. Last one, there are no plans to resell.
