MIDDLEBURGH — For the next two months one of the new display cases at the Middleburgh Library will showcase artwork by Scott Keidong. (You may have seen some of his work — photos in the Mountain Eagle and Times Journal newspapers, and the Timothy Murphy scarecrow in front of the library most recently.) The display includes photographs; relief prints ; collages; sculptures ; ceramic pinch pots; assemblages; a painting; and a variety of old, krappy, and pinhole cameras.
