Mr. Postmouse has loaded up his wagon and is ready to deliver the mail. From the lofty heights of the BirdsÕ tree houses to the inky depths of Mrs. OctopusÕs ship, the intrepid letter carrier lets nothing stand in the way of his deliveries. Each spread features whimsically detailed interiors of creaturesÕ homes, which readers will pore over for delightful surprises. This is a charming introduction to the postal system and an imaginative survey of different types of homes.
