Cloth lightly flecked, with a few corners lightly bumped; the fourth volume has the bottom edges of the boards a little more heavily bumped, with associated minor creasing to most bottom margins; the second volume has a few tiny dark marks to the leading edge and margin of a handful of leaves, and two tiny chips to one leaf (a production flaw); an excellent set with all four dustwrappers in excellent condition (spines lightly sunned and pulled a little at the top, with a small piece missing near the foot of the first one).
Charles Mountford was the leader of the expedition; he was also the author of the first volume, the editor of the second, and co-editor of the third with R.L. Specht (who edited the fourth volume). The first two volumes of this set were inscribed and signed by Charles Mountford in 1963 to Fred Klix. The recipient, a well-known South Australian artist, was also Art Director of Rigby Limited (circa 1965-75), when the Company published numerous books by Mountford.
