This collection was developed during the 2018-2019 academic school year as part of a project by University of Miami Library Research Scholar and then senior, David Lanster, who was carrying out research on yeast genetics and metabolism for UM's Department of Biochemistry & Molecular Biology. His goal was to contribute to studies on the cultural and social impact of food history in South Florida by examining food through the lens of various local craft breweries in Miami, which have been perfecting their own craft beer recipes for years. His collection contains advertisements, posters, flyers, beer caps, bottle openers, bottles, glasses, beer taps, and other ephemera and clothing items related to Miami's local craft brewery scene.

This collection currently contains advertisements, ephemera, pamphlets, scrapbooks, and graphic materials from National Airlines, mostly dating to the 1970s.

"Original artwork, including penciled sketches and watercolor mock-ups of small posters, created by this California artist for the San Francisco-based shipping line, The Grace Line (working here through a local advertising agency). The bulk of Ramm's art and papers were donated to the Smithsonian's Archives of American Art in 1994; subsequently, little of Ramm's work has appeared on the market. The group of work for a specific advertising campaign in 1931-1932 includes four watercolor mock-ups of posters/store cards from the Grace Line's 'Havana and Return' cruise; watercolor mock-up of poster for Grace Line's 'California to Victoria and Seattle cruise;' watercolor painting of an untitled cruise ship sailing along a rock coast; Ramm's scrapbook for art created for Grace Line menu cards; plus nine different sketches on tissue paper, being Ramm's rough drawings for menu card ideas." -Marc Selvaggio, Bookseller, A.B.A.A.
