1970-1985. A complete 3 volume set. All 3 volumes are in near fine condition with the only marks being a small ink date to each of the half title pages. The d/w's are all unclipped and very good with light edge rubbing. All now covered by protective covers. Volume 1 is a 6th impression, Volume 2 is a 2nd impression and Volume 3 is a first impression. A really lovely set. Scans available if required.
