Founded by Nathaniel Currier in 1835, Currier & Ives was the major poster firm of the nineteenth century. James Merritt Ives joined Currier in 1857, and the two produced some of the most popular images of the period through 1907—with the bulk of their work being done in the 1860s. Together they published thousands of prints, in three folio sizes (small, medium and large) of scenes that are still sought by collectors today.
