Well, why not? Antiques are certainly as interesting and no more expensive than stamps. There's a lot of teen age money around and often more collector's know- how and instinct than the group is given credit for. Mrs. Cole has published many adult books about the antique mania and she does very well by this audience, too. What is especially good about her approach to the possibilities of antique collecting is the secondary place she gives to value in dollars and cents, and the first place that she assigns to beauty and satisfaction. She covers such matters is where to get antiques, how to attend a sale intelligently and suggestions for specializing. There is a long, but clear, glossary, and a short but sound bibliography, to finish up a good book. Worth collecting.
