"Trading cards may be best known as a popular form of entertainment. But a set of cards in our collections was used to educate those who could not be reached through more traditional methods during the AIDS epidemic.
... The cards feature a variety of HIV-AIDS information and organizations, as well as personalities who died from AIDS, were currently battling the disease, or were involved in AIDS awareness. The cards depict individuals like Queen's Freddie Mercury, fashion designer Halston, lawyer Roy Cohn, and founder of the Pediatric AIDS Foundation, Elizabeth Glaser. The back of the cards provide more information on the individual, topic, or organization depicted on front."
