Apparently there has been a search for a mint copy of the original 1965 Electronics magazine in which Moore’s article proposing Moore’s Law appeared. Well, now a copy has been found, see BBC NEWS | Technology | Moore’s Law original issue found. It was under the floorboards of a hoarder. (Why under the floorboards and how was it found? Because his wife complained about the mess!) Double thanks to Judith Altreuter for alerting me to this and then pointing out a typo.
