In checking back through my archives, I discovered that I have not yet posted a vintage ad for THE PIPE. Please forgive me for what I am about to do.
So there it is. The most egregious, atrocious, horrific excuse for a pipe that ever existed. The ultimate gimmick pipe. THE PIPE was made from phenolic resin, with an inner bowl liner of pyrolytic graphite. It was available in every color imaginable, and many more hues unlike any known colors of the normal spectrum (avocado green?--hoark!). THE PIPE could be cleaned with soap and water. Or you could just remove the stem and blast it clean with a blow torch, since it could survive temperatures at 4,000 degrees Fahrenheit.
I don't have an exact year for this ad, but with the Fillmore poster font at the top and the "what's your sign" theme, I think we can safely say: 1973, about 8 minutes before disco was invented.
