I purchased from an antique store an apparently unopened box of a
half-gross of these cards. The date on the bottom of the box is Nov. 1,
1918. From Google it appears that M-Q developer was used to develop prints
on these cards.
What are the chances that prints can be made from this paper? Would Dektol
be OK? What dilution? Can you suggest a better developer? With
benzotriazole, or something else.
Thanks for any info!
