Terence Mitchell is a collector and expert on collectible cigarette cards. This collection contains a wide assortment of trading cards, collectible silks and fabrics, pins, and tobacco cartons and packs acquired by Mitchell. Most date to the early twentieth century.

Collection consists of thousands of cigarette, tobacco, tea, and foodstuffs trading cards, arranged by topic or set; hundreds of silks, blankets, and pins also distributed as collectibles through packages of tobacco; and about fifty original packages and tins of tobacco products, dating from the late nineteenth to late twentieth century. Mitchell created and accumulated substantial documentation of the items in this collection; that description has been included when available.

The largest series is the Trading Cards, which largely date from the twentieth century and include both American and international sets. This series also contains a sampling of nineteenth century cards from companies such as Allen and Ginter; W. Duke, Sons and Co.; Kinney Bros.; the American Tobacco Co.; Gail and Ax; P. Lorillard Co.; and others. There is typically one card from a series and they have not been sorted or further described.

The rest of the Trading Card series is arranged by card set, including sets from tobacco companies (including Will's Cigarettes, Ardath, Barratt and Co.; Gallaher Ltd.; Sarony and Co.; John Player and Sons; Turkish Tropies; Hassan; Mills Filtertips; Godfrey Phillips; Stroller's Cigarettes; Carreras; and others), tobacco monopolies (like the Imperial Tobacco Co. (of Great Britain and Ireland) Ltd.; American Tobacco Co.; and others), and other trading card sets from other brands and products (such as Brooke Bond Tea; Hoadley's Chocolates; Stamina Clothing; Shell Corp.; Nabisco; Sanitarium Foods; and Arm and Hammer). These came pre-sorted by Mitchell into various topical categories, which have been retained.

The second series encompasses the other formats of tobacco collectibles acquired by Mitchell, and include silks, blankets/flannels, and pins. These are arranged according to their S and B numbers, as initially cataloged by Jefferson Burdick.

The third series contains original Tobacco Tins and Packages, with assorted tobacco products including cigarettes, cigars, plug tobacco, and other related products from various brands and companies. These date from both the nineteenth and twentieth century.
