The late nineteenth-century equivalent of modern baseball cards were chromolithographed cards of important events and famous people, including notable scientists and medical practitioners; the reverse of such cards contained information on the contributions made by these individuals. Examples include this card of Andreas Vesalius, the anatomist who made extensive use of dissection in delineating the structure and function of the human body. William H. Helfand, from The Picture of Health: Images of Medicine and Pharmacy from the William H. Helfand Collection (1991), p. 121.
