Allen and Unwin. all 1966 2nd edition, 1st printing. 1966 was the first printing of the second edition produced for copyright reasons for the Ballantine paperback license problem.They needed a new edition. The 1966 edition failed to make all the correction Professor Tolkien required and he insisted they re-print them immediately for 1967. Thereafter we see most of the key text changes and it remain as we see them today. Both the first and second printings are must-haves for any collection. They later printings were just re-prints and not as important as far as content corrections. This set is looks like it has been together since purchase. Books and Jackets have uniform wear, bright covers, but much fading to the spines. Wear to spine corners and ends, scuffing to edges, TT has slightly more wear than the other two. Above average overall. Books have scuffing to clothe edges, well read, but solid. Overall, a very affordable set of the now rare first printings of the second edition.
