Unwanted gift. This is the review from Barnes and Noble's Website: 'This unique coloring book features immersive aerial views of real cities from around the world alongside gorgeously illustrated, Inception-like architectural mandalas. Artist Steve McDonald's beautifully rendered and detailed line work offers bird's-eye perspectives of visually arresting global locales from New York, London, and Paris to Istanbul, Tokyo, and Melbourne, Rio, Amsterdam, and many more. The adult coloring book's distinctive large square format offers absorbingly complex vistas to color, the crisp white pages are conducive to a range of artistic applications, and a middle margin keeps all the artwork fully colorable. Complementing the cityscapes are a selection of mind-bending labyrinthine architectural illustrations for still deeper meditative coloring adventures and imaginative flights of fancy'.
