I collect magazine paper dolls from women's and children's magazines, circa 1900-1930s.
Whenever I go antique hunting in shops, I look for interesting vintage ephemera and autograph books; and if the price is right, Victorian photo albums. Since I am a book artist, I also look for vintage handmade books.
I am particularly fond of lusterware, and limit myself to collecting lusterware condiment sets (sets usually include salt, pepper & lidded mustard pot with porcelain spoon, usually on a tray) shaped like birds or animals. I also look for teapots shaped like animals.
