One of the items dropped by Klaus Kerner at the beginning of the Fate of Atlantis is this old copy of The National Archaeology Magazine.
The front cover is replicated from a vintage National Geographic, with articles fitting to both the time period of the periodical as well as within the fictional world of Indiana Jones. The inside pages are lipsum text, except for one spread, copied carefully from the image of this prop in the computer game. The article tells of Indy's dig in Iceland and its connections to the Atlantis myth.
The entire magazine is aged to match its date of August 1929. On the back is a vintage style ad for the Herbert Johnson "Poet", the fedora made famous by Indiana Jones.
