;Fourth Series: During 1976 a completely new series of notes was introduced, with the exception of the 1-taka note, which was released as the second variety of the third issue during 1976. The notes of this issue are notable for the absence of the portrait of Sheikh Mujib, whose portrait had dominated all issues of the Bangladesh Bank until this issue. Instead of the familiar portrait, each note has an illustration of the Star Mosque on its front. 50 and 500 taka denomination was added in this series. 5,10,50 and 100 taka denominations were printed by Thomas De La Rue. 500 taka notes were printed by Giesecke and Devrient of Germany.
