The first flag was designed by Student Leaders of Shawdhin Bangla Nucleus painter was Shib Narayan Das and was made from clothes donated by the owner of Apollo Tailors, Bazlur Rahman Lasker, of Dhaka’s New Market. On 2 March 1971, the initial version of the flag was hoisted in Bangladesh for the first time at Dhaka University, as the Vice President of Dhaka University Students’ Union (DUCSU), student leader A. S. M. Abdur Rab, raised the flag. The flag was conceived so as to exclude the crescent and the star considered as symbols of West Pakistan. According to CIA World Fact Book, the green used in the flag represent both the lushness of the green landscape of the country and also the traditional colours of Islam. The current flag resembles the flag of Japan with the background a different colour and an offset sun.
The map was removed from the flag in 1972. One reason given was the difficulty rendering the map correctly on both sides of the flag
