Thanks, guys. Walking Eagle, the puppets are modern, probably less than five years old, made for the tourist trade, and in good shape. I've been keeping them in my desk drawer, so they live in the same temperatures I do. They aren't packed or wrapped in anything, just laying on top of the unsharpened pencils. I figured they's be protected from dust and light there, but have air circulating gently around them as well. Plus, I'd be able to look at them whenever I wanted to. I'll be interested to hear what Bill Sables and others have to say, but I can pick up some neatsfoot oil this weekend, and your application instructions sound right; these things are thin, and I want to preserve them, not marinate them. They'll probably stay in my drawer, away from the acids found in paper and cardboard, safe from dust, cats, and kids. No way am I going to put them behind glass in a picture frame and let them fade on a wall somewhere.
