An attractive Venezuelan import: Se?ora Amelia would like to grant her handsome pet's birthday wish to be the very first bicycle-riding hen. It seems impossible: bikes for hens aren't available. Fortunately, an itinerant inventor happens by in time to design and make one, just in time for Rosaura's birthday. The mellow, affectionate illustrations here nicely convey the humor- -and also provide a believable bike, of wood. A pleasantly offbeat story of cheerful persistence solving an apparently unsolvable problem. (Picture book. 4-8) -- Copyright c1991, Kirkus Associates, LP. All rights reserved.
