The 1971 paperback Hobbit by Unwin, an interesting cover featuring what appears to be a rough version of Tolkien's own illustrations, in this case Smaug over a burning Laketown.  This is accompanied by a fun 1989 Armenian version of Fellowship, printed by Yerevan - the interior illustration in which a Nazgul appears to be wearing a cowboy hat is quite a hoot.  Along with them in brown is a very furry-legged Bilbo in a 1976 Russian translation of The Hobbit published by Detskaya. - see the possible jacket for this 4 pages ahead.
