Several more of this type of cachet has come to my attention in the past couple weeks. I believe most or all of these were printed by Mike Bean, a former plate printer for the Bureau of Engraving & Printing. He has his own intaglio press and was able to print high quality engraved products from his home workshop.



The Washington 2006 cachets are unused, but I think they were intended for FDCs of the three stamps released as a souvenir sheet at the show: Scott 4075. I would be interested in seeing cancelled examples if anyone has them.
