Challenged with large, awkward sizes of maps and newspapers, we created a solution by enlarging our academy folder to give utmost protection to oversized materials. Made of 60 point sandstone archival board, brown acrylic coated Library Summit and a clear, chemically stable 3 mil archival polyester film interior L-weld envelope, the enclosure provides flat, safe storage for easy front and back viewing of materials. This enclosure works well for prints, stamp collections and storage of thin magazines or oversized pamphlets. As with all folders, custom sizing is available. Contact us for a price quote.
