Lodima Archival Materials: Originally based in Philadelphia as Superior Archival Materials, Lodima took over the mat-cutting business from Al Geiser and Son Custom Bookbinding. In 2009 we moved the equipment to our studios in Bucks County, Pennsylvania, in order to have ArtCare archival mat board (the only type of mat board the Library of Congress and the National Archives use), and computer-cut overmat services readily available for ourselves and to provide these materials and services to others. In 2013 we constructed an addition to our mat-cutting studio to house our 8×10-foot, 5, 000 pound, 1948 Seybold guillotine, and we have now expanded to offer frames and framing supplies of the same type we use ourselves.
