The Window Series began in the late 1970s as a series of value and color studies. “Waldrum's window forms were refined into three concentric rectangles representing the wall, the frame and the window opening. He was intrigued by the way that wooden window frames appear to float or loom suspended on the broad adobe walls of northern New Mexico. Up against the full and smoothed, earthen surfaces of adobe, such windows are usually painted a sharply contrasting pink, blue or turquoise and take on a heightened brilliance in the Southwestern sun.”1
