This online exhibition showcases the collection and career of Boston lithograph firm Louis Prang & Company, within the collections of the American Antiquarian Society. Featuring prints, salesman's samples and progressive proof books, this exhibition tells the story of Prang during the height of his career in chromolithography during the second half of the nineteenth century. Prang pioneered developments in the chromolithographic process, creating painting-like prints for the general public. He is also considered the "Father of the American Christmas card" having introduced it to the American public in 1874 after the wife of an agent suggested the idea to him while he was promoting his business abroad. Instrumental in the promotion of art education for public school students, Prang helped develop curriculum for schools, teaching art instructors, and creating safe, quality art supplies for students.
