Pawprints Greeting Cards, Inc. was a family-owned company with Wally’s then-wife Marcy Tripp at the helm as CEO and Art Director from 1978 to 1992. Started as Hey Nonny Notes in 1970, then Workshop Press, Pawprints was located in Jaffrey, New Hampshire. Sparhawk Books was an offshoot of Pawprints and published Wallace Tripp's Wurst Seller and Bad Child's Book of Beasts, among others. A successful company for over 20 years, Pawprints was the first line of greeting cards carried by Barnes and Noble. As Wally's Parkinson's Disease progressed, the company wound down and sold off its remaining stock to Recycled Papers, which later dropped the line. The cards are no longer in print. Wally illustrated over 600 cards, several calendars, coloring books, posters and various gift products. Several exceptional illustrators also contributed to the Pawprints line, including Trina Schart Hyman and Lynn Munsinger.
