From their website: “Stamp collecting ranks among the world’s most popular hobbies. As many as 22 million people collect stamps in the United States alone. Stamp collectors represent all ages and walks of life. Some have very general collections; others focus on special topics. Most are intrigued by the diversity of people, places, and objects illustrated on stamps. They want to learn where and when stamp were issued, who designed them, how they were printed and used. To these collectors, stamps bring history to life. Most of all, people collect stamps because it is fun.”
