Postcard mailing and protecting.

Postcards, photos and many other antique paper items are easily damaged, and are usually not replaceable. It is the obligation of sellers and senders to handle them very carefully. Aside from the obvious dangers to paper from liquids, heat, high humidity, and sunlight, there are three enemies of paper I wish to emphasize in connection with sending and protecting:1. Avoid all adhesive tape or scotch-type sticky tapes in or near postcards, because they are liable to cause irreversible damage. Don't use them to seal holders or sleeves with postcards inside, because while removing the card it might contact the sticky surface. If any tape at all is needed in packing, use one that leaves no residue, such as drafting tape or painter's tape, which is gepletely peelable. Scotch tape and other adhesives also ruin the stiff plastic holders sometimes used for postcard storage and shipping because it coats them with a sticky residue.
