We have created several products for Smithsonian Books over the years, including Smithsonian Baseball, an in-depth, lavishly illustrated look at the fascinating world of America's most avid collectors of baseball memorabilia, as well as a pair of highly entertaining trivia books, one on presidential history and the other on the history of air and space exploration, both volumes based on the Smithsonian's peerless collection of objects associated with those two topics. All three projects were highly successful in the marketplace.
