Keystone Triptych: Unframed digital vector print by John Miller. Image 10 x 36; no mat. These images were part of the Meander series. In April of 2007, River Arts, Inc. issued a call for proposals to artists for an original work of art which would address the boundary, place and space themes of the Smithsonian “Between Fences” exhibition. John Miller’s proposal was chosen. Inspired by antique maps and using that form as a template, John created A Sauk Prairie Meander.
