I was playing around in Photoshop and came up with this in an hour and 30 mins.
I took inspiration from the 100 Naira note and copied the security chipset on the 50 pound note and added custom guilloche patterns.
Meanwhile, a twitter user, Uncle Wali blasted him for omitting the Arabic inscription.
Then Arabic Inscription removed. This shows the kind of person you are. Bigoted, Tribalistic and Hypocrite. If truly your work comes within the depths of intellectuality, then out of sheer respect you won't mind putting the Arabic.
Shame on you!!!!
