Cachet

In philately, a cachet (French pronunciation: [kaʃe]) is a printed or stamped 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 both official and private (independent of postal authorities) cachets.

The first cacheted FDC (first day cover) was produced by prominent philatelist and cachet maker George Ward Linn in 1923, for the Warren G. Harding memorial stamp issue.

[citation needed] Cachet-making 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.

The largest and best-known cachet-making companies, which typically produce thousands or tens of thousands of printed cachets for U.S. stamp issues, are ArtCraft (1939–2015),[2] Artmaster, Fleetwood, House of Farnam, and Colorano.
