For an undisclosed client, but in a very exciting location in downtown Philadelphia , these solid walnut bookcases are absolutely one of a kind. Shop made blackened steel bases support the long cases, and live-edge, bug damaged slabs float over blackened case tops. These were designed for an art advisement company overseeing the project, and there were sketches and samples sent back and forth until we agreed on the eventual design for these five long bookcases. Two pairs live end to end, becoming very long spans, and one stands alone. They are so beautiful! The black walnut and black stain are quite nice together.
