MARK J. RETKA: SCULPTURE.  Mankato State College, circa 1974.  Medium softcover.  The orange folder contains 13 loose-leaf pages.  Illustrated in black-and-white.  The page with a photo of the artist is also signed by the artist.  Very Good+ condition.   Just a tiny bit of light edge-wear to the folder and a few of the loose-leaf pages.  A scarce title.
