Cachets can be official or private and they commemorate everything from political opinion, to specific routes, or the Super Bowl. Cachets for first day covers (FDC) made their appearance in 1923. Prominent philatelist and cachet-maker George W. Linn created a design for the Harding Memorial stamp issue. With this creation, Linn created an entirely new collecting area, and for many years, through his firm, Linprint, printed and sold first day cachets.

Most cachetmakers repeat certain elements in each design they produce. It could be a border, or the basic design of the cachet, or distinctive typography. One cachet designer well known for continuity of style is F.R. Rice’s whose lifesaver-style border is found on about 75% of his designs. C. Stephen Anderson’s cachets consistently feature an illustration with an historical narrative printed below it.
