Over the summer of 2012, RO/LU were artists in residence at the Walker Art Center in Minneapolis. For part of their project, “When Does Something, Become Something Else? The Apparent Is The Bridge To The Real,” the studio recreated works from the Walker's Collection, including Yellow Knot Prototype (1985) by Sherrie Levine, with International Klein Blue paint. Originally an edition of 50, only 14 were produced.
