Whenever any special stamp is issued, along with its First Day Cover with befitting cachet, a publicity brochure or an information folder is also brought out. It contains a brief write-up on the subject, designs, name of the designer and also technical data of the stamp. The brief write-up provided in a folder enlightens us with appropriate details of stamps which may be presenting politics, history , prominent personalities, national and international events, geography, flora and fauna, agriculture, science, monuments, soldiers, warriors, scientists, arms and ammunition, modes of transport etc. Thus process of learning becomes more delightful through visuals and brief write-ups. In addition, it cultivates a meticulous and focused attention to detail. It should, however, be noted that till 1962 these Folders were issued by Postal Department as publicity material. They were meant for promotion of sales of new stamps, and hence they were distributed free.  But, since these contained useful background information on the themes of the issues and technical data on the stamps, there was a gradual increase in their demand. The first Folder with price of 7 Naye Paise was published with the Red Cross Centenary issue of  8-5-1963.
