IN "Everything's Rosy," O. Soglow of New Yorker fame has made clever use of the physical device of color filtering. It is no new invention; it has been used in color printing for twenty years, and during the war Germany used it to disguise identification numbers on aeroplanes; but its use for humor is entirely original.

Each picture is, to all appearances, quite innocent and uninteresting except for the distinctive style of drawing O. Soglow has developed. Upon application of the filter, hidden lines appear which make the situation first depicted ludicrous or amusing in some way.

"Everything's Rosy" includes some of O. Soglow's cleverest ideas. The picture of Lady Godiva, for instance, is in his best salacious vein. And all New Yorker readers should howl with laughter over the new antics of that inimitable king of O. Soglow. But once in a while, one has the feeling that the humor is strained. O. Soglow has hoped that his name would excuse bad ideas, or perhaps that his drawing would put them over, which it almost does.

Whether or not the book justifies its price will have to be decided by the individual buyer.
