Dietrich’s commercial ventures extended beyond textile and wallpaper design to include greeting cards, posters and placemats. Starting in the late 1960s, the Duncan McIntosh company began reproducing a select number of his oil paintings to create a line of Christmas cards and notecards. Subject matter for Christmas cards ranged from nativity scenes to winter wonderlands, while notecards depicted floral fantasies, figurative works, cityscapes and harbor scenes, among others. In the 1980s and 1990s, Dietrich introduced his own line of notecards and placemats (known as “ARTMATS”), incorporating floral fantasies, racehorses, polo players, regattas, golfers, and other figurative works from his oil paintings and oils-on-paper. It was also during this time that he introduced limited-edition posters based on this subject matter that also included Native American life on the pueblo.
