Events, personalities, animals, birds, you name it and they have it. The philatelic bureau at the General Post Office (GPO), Chandigarh, has nearly 4,500 registered philatelists who keep in touch with the bureau for all the new issues of stamps.On average 5-6 people visit each day. They are either beginners or people from out-stations who do not have such bureaus in the post offices of their city.
Punjab has five philatelic bureaus located in Chandigarh, Amritsar, Ludhiana, Patiala and Jalandhar. There are two kinds of stamps internationally, definitive and commemorative. Commemorative stamps are those which are issued once on special occasions and in a limited amount. They are usually issued on the death and birth anniversaries of famous personalities, state and national animals, plants and other special occasions.(Source-Indian Express 13 June 2011)
