One Thousand Peso banknote issued in the Philippines during the Japanese occupation
As inflation crept in, the Japanese printed banknotes in larger denominations. This bill is the last of the third series along with the 100 and 500 peso JIM. It was printed just before their surrender in 1945.
Due to dwindling resources, this banknote is smaller than the others and is printed on cheap paper, the reason why the blue ink at the front bleeds through the back.
