Green Apple Watercolor Drawing Signed LEH serving utensil What I am not certainI believe this watercolor was likely done as a school exercise, but I find it pretty transcendent, and very Japanese feeling in its perfect simplify. Lovely. Paper is 12" x 9 and shows an old horizontal center fold and tears to the top right corner edge and staining at lower right, but with a mat over it, cut close to the beautifully wavering thin black border of the drawing, it would look just right.
