Mike ... thanks for the recommendations. I do have one question. The last two cards I soaked (post-war 1950's cards) ended up a bit warped. What is the best way to prevent warping? What I currently do is put the card between a thin wash cloth ... immediately after a soak ... and put the card between two very heavy books ... the top book being the heavyist. The first day I replace the wash cloth with another wash cloth at least once ... sometimes twice. After that I replace the wash cloth about once a day for about a week ... or until I'm sure the card is dry. But the last two cards I did I noticed near the end of this process (of being between the books) the card started to exhibit a bit of a wavy warp. I used to use paper towels instead of thin wash cloths ... but I've had a few cards stick to the paper towel. Maybe I didn't get all the glue off the card. But now I don't want to use a paper towel as it means re-soaking the card to get the stuck paper towel off. Plus ... if it IS glue still on the back ... I can't see it and am afraid to try to rub it off as it soaks ... because it might tear the surface of the card. Just curious. Thanks. Jerry.
