The Land That Time Forgot

Grosset & Dunlap reprinted in 1925 using the same 422-page text and the St. John jacket, but with only THREE interior plates against the McClurg first's four — plate count plus the G&D imprint is the tell. A second, subtler trap: Ace Books split the omnibus into three separate paperback volumes in 1963, so a volume titled 'The Land That Time Forgot' containing a single novella is a 'first thus' at best and never the 1924 first. No book-club issue is documented.
