The Encyclopedia of Black Collectables says Currier and Ives was a well-known 19th century printmaker. They painted quite a few black subjects. Nathaniel Currier perfected hand-coloring black and white stone litographs and started his print business in 1852. They published many political and humerous prints that they "believed to be true".
