Instructions
Choose archival-quality storage materials for your vintage postcards. Archival quality means that the storage material reduces damage caused by handling as well as the environment, and doesn't introduce chemicals that can damage the vintage items.
Look for openings in albums and holders that are somewhat larger than the postcards themselves. It's very easy to crease or bend a postcard while trying to squeeze it into a holder.
Find albums or holders with plastic made from non-PVC or uPVC, which is considered to be archival quality. Special postcard holders are available. Check out the vintagepostcard.com website for more information.
Search for paper album pages and storage boxes that are acid-free with a pH of 7.0 or higher. Many of the papers manufactured have added chemicals, leading to a high acid content that can discolor vintage postcards and cause them to become brittle.
Remove vintage postcards from old albums carefully, especially if the postcards were mounted on green or black construction paper. The colored paper may leave a residue behind on the corners of the postcards.
Frame your vintage postcard collection, but be sure to keep your postcards out of direct sunlight. Instead, show them off on an interior wall in your home.
