This is the first page from my stamp album carrying stamps of Pakistan. At the time of independence in 1947, readily no indigenous stamps were available. Therefore the old British India stamps with overprint PAKISTAN were used. It was almost a year later that a set of four indigenous stamps (top right corner) was issued in 1948.
In the bottom right corner are the stamps of the independent state of Bahawalpur. The state later merged into Pakistan in 1954.
