Yale University Press, New Haven, 1950.  First edition, fourth printing in second printing dust wrapper.

A very good, tight (likely unread) copy in a very good dust wrapper.  Book's spine a little creased and mottled, one small closed tear to top, negligible bump to front corners.  Though dust wrapper is marked as second printing, it does not give the appearance of having been "married" -- or at least the mottling on the book's spine postdates the marriage, as the dust wrapper evidences the same pattern.  Some chipping to spine tips and lower front flap, slight creasing to lower front panel.

Human Action is a classic in the Austrian School of Economics and one of the most influential works on free market economics of the twentieth century.  As von Mises' friend and mentee, Friedrich A. Hayek, said in a review of the earlier German version: "There appears to be a width of view and an intellectual spaciousness about the whole book which are much more like that of an eighteenth century philosopher than that of a modern specialist. And yet, or perhaps because of this, one feels throughout much nearer reality, and is constantly recalled from the discussion of technicalities to the consideration of the great problems of our time. ... It ranges from the most general philosophical problems raised by all scientific study of human action to the major problems of economic policy of our time."
