Everyone's favorite stuffed animal, the teddy bear, has come out of the nursery and into the antique shop. Teddies were named after President Theodore Roosevelt, who supposedly refused to shoot a stray bear during a hunting excursion. Bears have been manufactured since the early days of last century and now are collectors' items. Antique bears—those made before 1940—are more expensive than the recent versions, of course. And if you're a serious hunter, interested in bear lore and collecting, you've got your choice of teddy bear clubs to join.
