Show moreWithin the advertisement collection is a range of materials from broadsides, handbills, and posters, to newspaper ads, couriers, and trade cards. Also included are booklets and programs that were mainly intended as promotional material with the informational content having a subsidiary role. (Please find informational booklets and programs in their own sub-collection folders.) Circus posters are also in this collection since their purpose was to advertise. Note that there are two large poster collections in addition to several individual posters. Also see the prints and the photographs collections for several items that are similar to posters, but smaller. Show less
