Sudan Banknotes with Mini Maps

Several banknote denominations and years have solid or outline shapes (simplistic maps) of SUDAN on them. Images of Sudan's shape first appeared on the center of banknotes printed in 1981. The banknotes with Sudanese shapes on them are as follows: 25 and 50 Paistres, 1 Pound, and 2, 5, 10, 20, 50, and 100 Pounds. In 1981 and 1983, a Secretary Bird (Sagittarius serpentarius) was superimposed on top of Sudan for all aforementioned banknotes except the 20 Pounds (1981) and 50 and 100 Pounds. The Secretary Bird appears on the current coat of arms, signifying its official national bird status in Sudan. 50- and 100-denominated banknotes did not exist yet in those years, while the 1981 20 Pounds note is a realistic map featuring Sudan's major rivers. After 1981 and 1983, banknotes featured the Sudanese shape without the Secretary Bird on top of it. From 2006 to present, the 1 Pound banknote's obverse side features a larger stylized Sudan (center) and a smaller Sudan (top-right corner).

Geography
Formerly Africa's largest country, Sudan fell to third-largest after Algeria and the Democratic Republic of the Congo when South Sudan gained its independence in July 2011. The White Nile and Blue Nile rivers flow vertically through southeastern Sudan and join each other near the capital, Khartoum, to form the major Nile River. West and northwest of Khartoum is a city with a higher population: Omdurman. The Darfur region occupies western Sudan, while the Nubian Desert (As-ṣaḥrāʾ An-nūbīya in the Arabic language) is found in northeast Sudan. This desert is found north and east of the Nile River and west of the Red Sea. Starting north and going clockwise, bordering countries are Egypt, Eritrea, Ethiopia, South Sudan, Central African Republic, Chad, and Libya.
