Wired News reports on a new product offered by the United States Postal Service (USPS): PhotoStamps. The USPS already offered a service that let you print your own postage via its stamps.com site, and this seems to expand on that by letting you the upload your own photo to the PhotoStamps site in order to make custom stamps. Of course, it does cost more to make your own stamps than it would to just buy the same denomination (about $0.85 for a $0.37 stamp if you buy a sheet of 20), but I guess that's to be expected. Unfortunately, there are some pretty broad restrictions on photo content, which could (perhaps unjustly) prevent some images from getting made into stamps:

You further agree not to use the PhotoStamps website or service:
B. To upload, order for print, or otherwise transmit or communicate any material that is obscene, offensive, blasphemous, pornographic, unlawful, deceptive, threatening, menacing, abusive, harmful, an invasion of privacy or publicity rights, supportive of unlawful action, defamatory, libelous, vulgar, illegal or otherwise objectionable...

That's too bad, because it probably means you couldn't make some of the stamps that Boing Boing has come up with, although I think that you could still have some fun with this...
