David M. Pritchard, Jr. designed first day cover cachets for U.S., Canadian, U.N., and other stamps issues, beginning in the mid 1960s and continuing into the 1980s. Mr. Pritchard's early cachets lack the professionalism seen in most commercial designs, and perhaps that is why I am so fond of them. Most of the early cachets were mimeographed with typewritten text and hand-coloured with pencils or markers.
He identified his cachets with his initials "DMP" and later with the "David "C" Cachets" logo:
