The result of a seven-and-a-half-year undertaking to document Iowa's barns and all they represent, ""Harker's Barns: Visions of an American Icon"" featured seventy-five stunning black-and-white photographs by Michael Harker. An impressive and well-received collection, the book helped preserve the glory of one of rural America's most elemental icons. ""Still Standing: A Postcard Book of Thirty of Harker's Barn Photographs"" - some from ""Harker's Barns"", some previously unseen - continues that mission of preservation. Printed on heavy card stock and perforated for easy removal, the cards showcase Midwestern barns - from square to round, wood to brick, Dutch to Swedish, occupied or abandoned, all symbolizing a passing way of life that was once the lifeblood of Iowa and the Midwest. As barns continue to disappear, these images will endure. ""Barns Again! Celebrating an American Icon,"" an exhibit of Harker's barn photos (with text by Loren Horton) sponsored by Humanities Iowa and organized by the Smithsonian Institution's Traveling Exhibition Service and the National Building Museum, with assistance from the National Trust for Historic Preservation, is currently touring Iowa.
