Licensing

This image is of a United States postage stamp produced in 1978 or later. The copyright for it is held by the United States Postal Service. It is believed that the use of postage stamps

to illustrate the stamp in question (as opposed to things appearing in the stamp's design)
on the English-language Wikipedia, hosted on servers in the United States by the non-profit Wikimedia Foundation,

qualifies as fair use under the copyright law of the United States. Any other uses of this image, on Wikipedia or elsewhere, may be copyright infringement. See Wikipedia:Non-free content for more information.

Usage that does not fall under fair use requires a license from the USPS. This includes usage of the stamp's artwork to illustrate its subject, rather than the stamp itself.
