This is a beautiful and crisp example of a 1920's expandable book rack. The poem on one side is by Francis Bacon, the other signed Johnsoniana. It has a nice patina with noted wear for its age. When closed, it measures 13 1/2" long X 6 1/2" wide and 6 3/4" high on the sides. The book rack when extended measures 21".
