The stamps feature images of a map of the Suez Canal, along with photographs of a waterway in a desert setting which do indeed appear to come from Egypt.
However they also show another two lane waterway in a green, fertile landscape which bears an uncanny resemblance to the Panama Canal – the 48 mile Central American passage which links the Atlantic and Pacific Oceans.
The Suez Canal has long been an asset coveted by European empires and local Arab nationalists alike. It was once one of the gateways to the British Empire in India, but later served as the catalyst for the UK’s imperial decline after the failed attempt to retake it from Gamal Abdel Nasser in 1956.
Revenues from the canal, which total around £3 billion ever year, are now a hugely important channel of revenue for the Egyptian government.
Officials in Cairo announced their plan for a 45-mile extension of the waterway last month. The scheme will allow ships to travel in both directions for a section of the waterway.
But engineers have already run into hot water after it emerged that thousands of Egyptians have been evicted from their homes to make way for the bypass.
A government official, speaking to an Egyptian newspaper Youm 7, said that the postal service was aware of the mix up and was trying to rectify the situation.
