G. Graphics water pipes or bongs, were made in Milwaukee in the mid '70s.
They consisted of a thick acrylic tube in a variety of colors and lengths. The tube had a removable stem assembly that went through the tube and into the water.
The tube was embedded in epoxy and colored fish tank gravel in a soup can. The soup can was painted black, then covered in colored suede leather.
I'm looking for one for sentimental reasons and can pick up the weekend of 11/20 or can pay for shipping COD. Possibly you have one in a garage? Under the steps in the basement? In a box of old junk in a closet or the attic?
