I’m no philatelist but I do love a pretty stamp. Finding out there’s both a definition and an audience for these stamps kind of makes me want to make some.
As cinderella stamps are defined by what they are not, there are many different types and the term is usually construed fairly loosely. Items normally regarded as falling within the area are poster stamps, propaganda labels, commemorative stickers, stamps issued by non-recognised countries or governments, court fee stamps, charity labels like Christmas seals and Easter seals, most telegraph stamps, some railway stamps, some local stamps and purely decorative items created for advertising or amusement. Revenue stamps are sometime considered cinderellas, but as they are normally issued by an official government agency, they tend to be classed separately from other cinderella stamps.
