This is an original hand sketch of Wrigley, Tribune & Union Station located in Chicago, Illinois . The sketches are enclosed in thin lined boxes, creating object and field on the artist paper. Each illustration is labeled, dated, and signed. The delicate pen lines create texture and movement amidst every detailed stroke. The black and white sketch study makes a classy art piece ready to be framed. Sketches were created using archival ink pens, applied to drawing artist studio paper, natural white with pronounced textured surface - acid free. Please note: This sketch is not framed. It is laid upon a backer-board and packaged inside a clear bag ready to be framed with a molding of your choosing.
