Athol and Virginia Cliff of Millburn NJ had purchased Cachet Craft Cover Service from Frederick B. Fitts Co. in 1953. In 1971 Unicover Corporation of Cheyenne WY purchased Cachet Craft Cover Service from the Cliffs, and folded the Cachet Craft line into the Fleetwood brand of Cachets, which Unicover had purchased from Milnor and Travilla (Ioor) Peck in 1968, after the death of Travilla in 1967. The Last Cachet issued under the Cachet Craft brand was for Scott #1455, Family Planning, 3/18/72. (Monty et al., First Cachets Revealed, 2006, p. 85).
