Auction 333-341 Nigeria, Cameroon, Sudan & Worldwide Postal History - Day 4

Note: The additional 'One Penny' overprint reduced the local poundage to match the original. This was as a result of the reduction of poundage on 1 July 1947. All remaining postal orders were then overprinted with this reduced figure.
