An assorted threesome. The first is the "Illustrated edition" of the Hobbit with illustrations by David Wenzel, though the cover artwork is by Donato Giancola. The center one is TTT, first Polish edition by Czytelnik from 1961-63. Though the covers of this set were white, there was a colored fold or drawing inside.  The last one is a recent Polish edition of ROTK.  Thanks to Narquelie once more!
