Walt Whitman fans can peruse a number of of gems - including proofs, engraved images, and a handwritten letter to the poet from Ralph Waldo Emerson - with the University of Illinois Springfield's Walt Whitman Collection. This collection of 33 items, part of the Special Collections and Illinois Regional Archives Depository, contains a number of pieces authored by Whitman himself, including poems and the obituary he penned for his brother Jeff, "An Engineer's Obituary." The collection also includes a number of items that will appeal to those interested in the history of print culture, such as a stereoscopic photograph of Whitman; an image of the engraving of Whitman on the front piece of Leaves of Grass; and an advertisement page for a number of the poet's works. Finally, one can find a number of intriguing odds and ends in the collection, including the program and menu from Whitman's 70th birthday celebration at Morgan Hall in Camden, New Jersey. (The meal was dubbed "The Feast of Reason," and the main entree was broiled chicken with mushrooms.)
