Overprint Cinderella Stamp

Any new text, numerals, or design element printed on an existing stamp, thereby creating a new stamp. The overprinted stamp may have a different denomination or a different usage, or even be for a different country. There have been very few overprints in the U.S., but many other countries have issued them more frequently, prompted by change of government, hyperinflation, or frugality.
