Bills in the era of the 1960s and 1970s seem to feature Chinese workers and the reconstruction of China. This one features a Chinese made Truck in a series including a Plane and a Ship. They do not indicate the denomination on the bill in English. One student told me the size of the vehicle tells you which note has more worth. In this order Ship, Plane and Truck, 5, 2, and 1 Fen respectively. One Hundred Fen makes one Yuan.
This bill measures 3 7/8 by 1 7/8 inches. -- By comparison the US Dollar bill measures 6 1/4 by 2 1/2 inches
