1967 - 1976
David M. Pritchard, Jr. from Cincinnati produced and sold first day covers for U.S., U.N., Canadian and European stamp issues beginning in the mid 1960s and continuing into the 1980s. Pritchard identified his cachets with his initials "DMP" but in 1970 changed to "David "C" Cachets" following the birth of his son Chip.
Pritchard cachets are celebrations of philately. His Canadian cachets were mimeographed with typewritten or handwritten text and hand-coloured with pencils or markers.
