This Commemorative Suez Canal Stamp Has One Glaring Error
The Egyptian postal service had the best intentions when issuing a series of stamps to commemorate the Suez Canal and its multi-billion expansion project, only there was one glaring error: the stamp showed a picture of the rival Panama Canal (for those of you who don’t know, Suez Canal has no locks).
I wonder how many millions were printed before anyone noticed. It would be bad enough if they were similar but the Suez has no locks at all. Quite a difference!
