The New Yorker artist Ian Falconer's endearing charcoal portraits of his porcine heroine are spotted with fire-engine red gouache in all the right places--perhaps a tribute to Hilary Knight's red, pink, white, and black celebrations of Olivia's human counterpart? When she dresses up, the bow on her ears, her red lipstick, and her high-heeled shoes are all red. (The only time her shades-of-gray body is pink is when she is sunburned and the area where her bathing suit was is white!) Falconer does a fine job of letting the spare text set up the jokes for the visual punch lines--a dryly humorous interplay that adults will appreciate as much as children.
