n. the collection and study of postage stamps [syn: philately, stamp collection]
Wikipedia
Stamp collecting is the collecting of postage stamps and related objects. It is related to philately which is the study of stamps. It has been one of the world's most popular hobbies since the late nineteenth century with the rapid growth of the postal service, but is now in decline with the rise of the internet which has sharply reduced the number of postal items arriving in households. Stamp collecting proved to be an almost perfect hobby for collectors because there was a never ending stream of new stamps as each country sought to advertise its distinctiveness through its stamps. Because some stamps became rare, a thriving international trade in stamps was created. While stamp collectors are of all ages, it has been particularly popular hobby among children, many of whom continued the hobby as adults.
