Let's give a page to the Unfinished Tales.  On the left is a reprint of Ballantine's first paperback edition, in the center a hardback with maps (1980?)  and next to it, with Ulmo towering over the waves, is the Grafton UK paperback, 1991.  An iffy-condition 1982 Unicorn issue follows.   Tailing along at the end, the more recent 2001 Houghton-Mifflin hardcover.
