Attributed to Vincent Nardone.  Both pieces are signed in block letters lower right.  Found at an estate sale.  Not sure of the medium.  I could send more pictures if interested.  Both are in excellent condition.  The matte is a peachy color.  Very interesting abstract works of art.  One measures 5" x 4.5" in a 12" c 11.25" frame while the other is 3" x 5.5" in a  9.75" x 11.75" frame.  Wood frames are gold color.
