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.

It also refers to the collection, appreciation and research activities on stamps and other philatelic products.

For instance, the stamps being studied may be very rare, or reside only in museums. - A hobby is a regular activity that is done for enjoyment, typically during one's leisure time. Hobbies can include collecting themed items and objects, engaging in creative and artistic pursuits, playing sports, or pursuing other amusements.
