Three picture story books which, in days like these, are extraordinarily good. Thumbelina is newly translated by Paul Lyac and charmingly and delicately illustrated by Oscar Fabres.....Yussuf the Ostric has a distinctly modern parable quality which adults will appreciate, while the small fry will find the story hugely entertaining. Illustrated by the author.....The Magic Bd-Knob is more story and less pictures -- sub-titled How to be a Witc in Ten Easy Lessons. A fairy tale in modern guise, which might be better listed under BOOKS TO READ ALOUD, Almost another Mary Poppins, a beguiling yarn of enchantment, with unique twist. A very original tale....................All three books printed by Hyperion -- 4 pages in full color, well re-produced.
