Finnish Post has offered this kind of service for a better part of a year and a half now. It's mostly used by private companies, but at Christmas time some of these stamps ordered by private citizens were in circulation. In fact at Arctic Circle last Christmas season people had the option to get their photographs taken and a small run of stamps were offered to them after a short wait (ie. printed right on the spot). As an avid stamp collector, I've closely paid attention to the collectibility of these and as of yet they are frowned upon by the collectors and even big runs (thousands of stamps to companies) are not listed and (what I've heard) will not be listed in stamp catalogues. Whether or not they are STAMPS is not an issue - whether or not they are COLLECTABLES is the important question.
