Lithography 

Lithos meaning stone. A lithograph is a print made by drawing on limestone with wax crayons, applying ink onto the stone and printing the image onto paper. It often uses both oil and water. In order to use lithography, you have to make marks with a greasy medium and then dampen the medium so that the ink only sticks to the greasy marks.

Currier and Ives
They were a team headed by Nathaniel Currier and James Merritt Ives based in New York. They specialised in printmaking often using black and white lithographs with hand-drawn colouring. They published at least 7,500 lithographs in the firm’s 72 years of operation, artists produced two to three new images every week for 64 years but due to the mass reproductions, it became much harder to tell if the print was original or just a copy.
