I have a title page and 24 plates from Dr. Schubert's
Naturgeschichte des Mineralreich; Schrieber, Stuttgart.
I do not have a page with a date. The color plates show arrangements of
minerals, gems, and fossils along with numerous crystallographic line
drawings. They appear to be multiple-plate lithographs. Many are beautifully
handled with metallic inks. For example, "Dendrititsches Silver von
Kongsberg" sure looks just like silver on the plate.
Chromo-lithograph category perhaps. Ten power lens examination reveals color
patterns slightly off register from outlines but conforming to inked
plate--not freely hand colored.
My guess is 1885. Can anyone with Mineral Book knowledge nail the date down
for me, and give me a little information about the author?
Thank You.
