1969 original pop art serigraph. The piece entitled “Ralph’s Bubble Machine” is 6/7, pencil signed by the artist “Logan.” Oval composition featuring a series of female figures angled in varying positions revealing their breasts, profile, and back sides. A large male figure at right flashes an uneasy grin while his chest emphatically displays his heart. Perhaps this image is a celebration of the sexual revolution of the era or an anxiety in dealing with the new sexual freedom. The paper serigraph is framed with an acrylic pane protecting the art.
