Hirschl & Bendheim produced, I believe in the early 1970s, a line of "Color Cobs," which had the bowl and shank entirely painted, presumably to go with Dr. Grabow and The Pipe which had fashion-oriented models. I've seen Color Cobs in bright red, blue, green, etc., in some pastels like pink, and in early-70s colors like olive green. I've no idea how, exactly, they were painted, but they were (and they were cobs, not wood pipes).
