"This varied collection of approximately 2,500 prints offers a fascinating look into the history of medicine through popular imagery. The medium of the print, being an economical means of image production, allowed for the dissemination of pictures to a wide audience. Painted portraits and scenes could be drawn, engraved, and thereafter reproduced and circulated in large quantities. While only a select few could see an original painting, engraved prints could appear in publications, feature as frontispieces in books, or be sold separately" (http://digital.library.mcgill.ca/oslerprints/about.html, accessed 01-2017).
