I smells a hoax, an old one, but a hoax nevertheless. Comparison to the phoenician alphabet shows a decided lack of some of the more difficult to write characters and an abundance of the easy ones. Perhaps the good professor Frank Hibben was a self-styled expert on ancient Phoenicia looking for a legacy? At any rate, it's not far from here, so I may take a little day trip down there. Or as has been mentioned earlier, it may very well be the elusive original recipe.
I never attended UNM but that name sure sounds familiar. There was a UNM prof. who investigated the supposed Roswell crash site but I don't think this was him.
