Designed by Florence Knoll in 1948, this double letter tray is made of ebonized birch plywood and was a staple of mid-century office decor. The underside of one of the two stacked trays bears Knoll label with 320 Park Avenue address, indicating manufacture in the 1960s.

Each tray measures 2 inches high, 11 1/4 inches wide, 14 inches deep; overall height is about 7 inches.

Overall condition is good, with no splits, cracks or losses to the wood. Minor wear to the ebonized finish at the corners and edges; there is a smudge of white paint on the underside of the bottom tray. Some wear to the metal support. The top tray tilts down from the metal support in the back, typical for pieces of this vintage.
