Kon-Tiki (Kon-Tiki ekspedisjonen)

Thor Heyerdahl · Gyldendal Norsk Forlag (Oslo) · 1948

The original-language Norwegian edition (Gyldendal Norsk Forlag, Oslo, 1948) has clear precedence; both English editions are 1950 translations by F. H. Lyon and neither is the true first of the work. Both English editions are collected and both are dated 1950: the London Allen & Unwin issue and the Chicago/New York Rand McNally issue. A contemporary scholarly review in American Antiquity lists the two together without ranking them, and month-level precedence between the London and New York issues could not be established from the sources consulted, so neither is asserted here as "the" first English edition. The titles differ and are a quick shelf test: the UK issue is "The Kon-Tiki Expedition: By Raft Across the South Seas," the US issue is "Kon-Tiki: Across the Pacific by Raft."
