Architecture and city art posters reveal the appeal of building outlines, repeated windows and shadows across a street. A carefully observed corner and a scene simplified into roofs and coloured walls can both suggest the character of a place. Muted tones relate well to wood, while defined lines can connect with glass and metal objects. These images may suit a mood of imagined travel or an interest in familiar streets. Viewpoint is a useful distinction when choosing. A distant city view offers a broad scene, whereas a close architectural detail invites attention to a doorway, a facade or the rhythm of windows.
