There is truth and poetry in this allegorical story of four brothers, three who could do some one thing better than anyone else and the fourth who was a quiet one. When their friend, an old witch, promises them a magic feather duster which will satisfy all their needs, if only they will secure for her an apple from a crooked apple tree, the three crafty brothers confidently go after the boon. Each time, as they carry the apple away from the tree, a frog asks them for it. Each time they refuse. ""That is the wrong apple,"" says the witch and changes them consecutively into a rabbit, a mouse and a bear. Only the quiet brother grants the frog his request and it is to him that the feather duster is awarded. He meekly accepts his prize, disenchants his brothers who are somewhat haggard from their experience, and uses his duster as a proper duster should be used--to make order. Lyrical in concept and form, Nicholas Mordvinoff's expressive drawings and Will Lipkind's chastely moving text, work faithfully to achieve that high aesthetic quality which characterizes their work.
