Republic of the Philippines - Stamps and Postal History

Errors, Freaks & Oddities (EFOs)

- Offsets -

An additional unintended impression, in whole or in part, of the stamp design on the face or back of a stamp, caused by wet printing ink coming into contact with the surface that bears the additional impression.  Appears most commonly at the back of a stamp.  The design appears reversed that is, it reads from right to left, instead of from left to right.
