Trouble.
Small collection of pottery and porcelain, some Roseville, Lladro, Van Briggle, Hull, California Art pottery, some odd things. I've picked up quite a few at auctions. Bought a beautiful vase and wall vase (Roseville and Hull) at an auction house for $5.
If I had the means, I'd collect fountain pens, tarot cards, more art, especially from the Art Nouveau period.
