Very well said Steve, and you nailed it; I collect newspapers (Cascade Miner 1893 - 1912), which are notoriously brittle (usually fragments), and of poor quality, and strip cards which are not nearly the quality of T206's.

Dessicant packs work well as a dehumidifier which can be effective in limiting the growth of molds and mildew, especially in old Washington state newspapers.

I only have one T206 (Hunky Shaw) and had to look at it last night . Excellent quality, durable card. Really like the suggestions of scanning the card for display which would look great under glass on your desk. Best of luck on the monster!
