@hotpress1,
you give absolutely no valuable information here. The only hint I can give is whether the signature seems to be signed in the plate or is it in pencil below the plate margins?
Is the plate mark easily visible as an indentation all around?
Is the work looking like it was a print of a black crayon drawing?
Are there lines or masses of tone or color?
In the 1800's there were
etchings, aquatints, mezzotints, woodblock (other block too), silk screens, lithograph,collagraphs,photprints,gesso prints, glue prints, stamping, and several others I havent remembered.
Theres a great old book that's still a BIBLE in printing. Its the COMPLETE PRINTMAKER by John Roass and Clare Romano. I used it when I was in art school and it gives a working understanding of all kinds of old style porints (where the artist had a working relationship ith the orint). Another technique in which the artist (Usually) had nothing to do with the oprint was a technique called LINE ENGRAVING.
Each of these styles leaves an easily recognized foot print and if you are interested in prints (REAL PRINTS) not this graphic or giclee crap they do today, then Id say get Ross and Romano.
