The ""new"" antiques are the turn-of-the-century variety from the end of the Victorian Era in 1890 to the start of the modern in 1925. Ann Cole Kilborn, who writes a column for The Philadelphia Inquirer and has written previous books for McKay on antiques, is an informal, informative guide to the subject. There are all sorts of items for all sorts of tastes and a variety of values for a variety of purses. There are the furnishings of the art nouveau and Elbert Hubbard, Carder and Tiffany glass, Kaslun and Ysart paperweights, American Bellick porcelain and Rookwood pottery, By-Lo Baby and ""name"" dolls, mahjong sets and marbles. Then there are objects rich in nostalgia though negligible in value such as rolling pins and cuspidors, or fad items, souvenir and commemorative pieces. Finally there are the antiques of the future such as to the new Tobies and original Hummels. Of reproductions one must be wary: at best, they water the market and dull interest. Mrs. Colo has formulated a new concept of what's old and has opened up a fresh field for the antique hunter.
