2 Volume set in Good condition with Good -ish dust jackets, printed in 1951.  Covers show only light wear, BUT there's a little age-spotting to top edges of covers and a little on the top edge block as well.  Both dust jackets have some chipping at ends of spine and the History volume has a very long taped edge tear (not easily seen).  Inside pages clean with little or no obvious wear.  No Owner marks.
