Paper Based Collection Preservation Care Tips 5-6 | Avoid Exposure to High Humidity
Care tips 5-6 summarize how to protect your stamps, baseball cards, comic books and other art from exposure to (P)recipitation/Humidity.
Care Tip 5. If you choose to encapsulate or encase (slab) your baseball cards, comic books or stamps, you should do so with the understanding that a harmful “micro-climate” may become formed within the encapsulating plastic or glass material that is used. The sealed environment that is formed within such encasements/slabs can under many conditions accelerate harmful chemical processes that are inherent to the organic matter that your paper based rarities and collectibles are made from. If you choose to slab your stamps, comics or baseball cards, always ensure that they are provided with a means by which they can be regularly ventilated.
Care Tip 6. Store and display your comic, baseball card, and stamp and philatelic collections under as steady an environmental condition as possible, preferably at about 68 degrees F and between 30-55 % relative humidity (RH). Just as when you encapsulate a stamp or other collectible, if you choose to store them in a stamp album or other container, the container should be periodically ventilated to avoid mold and moisture formation.
