edition of 4 SOLD OUT. May of 1966 and I am a junior at Pratt Institute working way too hard and surviving on candy bars, spaghetti and cigarettes.One month later I was on the road crossing the continent and living in a 195? Chevy Impala Station Wagon with 2 other Pratt guys. One was lost in Yellowstone National Park...West Thumb, Wyoming as I recall. Arriving at Vancouver, Washington I began my brief but transforming life as a tugboat deckhand. Ah, but that story is for another time. White Ground is a mixture of soap, titanium white and linseed oil. It dissolves in the acid over time allowing for a chiaroscuro effect. Exhibited:?
