A Postage stamp design and error

This Philippine stamp of 1932 is captioned Pagsanjan Falls, but actually depicts Vernal Fall; compare the photo below.

A postage stamp design error is a mistake made during the design phase of the postage stamp production process. Design errors most commonly occur as minor mistakes, such as a missing letter in the binomial name of an organism depicted on the stamp, but some have been major gaffes, such as a map appearing to lay claim to another country's territory, or the depiction of the wrong person on the stamp.
