Be sure whatever sleeves you use that they say "archival", are acid-free, and contain no PVC! IMPORTANT: remove your postcards from the vintage postcard albums where the pages look like black or green construction paper. The acid in the paper will eventually damage your postcards (if they haven't already) and the slots will damage your postcard corners.
