Cachet
From Wikipedia, the free encyclopedia
In general terms cachet refers to "prestige", or a societal stamp of approval.
In philately, a cachet is a design or inscription, other than a cancellation or pre-printed postage, on an envelope, postcard, or postal card to commemorate a postal or philatelic event. There are official and private cachets; they commemorate everything from the first flight on a particular route, to the Super Bowl. Cachets are also frequently made, either by private companies, or a government, for First day of issue stamp events or 'Second-Day' stamp events.
The first cacheted FDC (first day cover) was produced by prominent philatelist and cachetmaker George W. Linn in 1923, for the Harding Memorial stamp issue.
Cachetmaking is considered an art form, and cachets may be produced by using any number of methods, including drawing or painting directly onto the envelope, serigraphy, block printing, lithography, engraving, laser printing, attachment of photographs or other paper memorabilia, etc. Frequently flight cachets (which have also been used in space and on the moon) are rubber-stamped.
The largest and best-known cachetmaking companies, which typically produce thousands or tens of thousands of printed cachets for U.S. stamp issues, are Artcraft, Fleetwood, House of Farnam, and Colorano.
