Australia: Short Paid Aerogramme

This Australian 12c aerogramme (Stein #A-39) was sent from WANNEROO 7 MY 74 to Hilversum, the Netherlands. The aerogramme rate in May 1974 was 14 c. Hence, the aerogramme was short paid 2c.

According to UPU rules a tax fraction should have been endorsed with double the deficiency (4c) in the numerator and the first weight step international surface mail rate (12c) in the denominator. However, only double the deficiency was endorsed.
