Large Hand Painted Factory Board Signed 1955

This conference room  work board is double sided and is freestanding and hand painted on both sides. One side is a huge gridded chalkboard with hand painted columns and you can still read some of the amounts entered on the board ( I left them as part of the piece) . Board is signed and dated on the lower right Ran 6-17-55. The other side has a flow chart with lots of small nails where they hung (I assume) tags that were labeled that were moved about on the piece. This would make a great object in a large room or serve as a nice room divider. Piece is made of oak that has a deep color and boards are trimmed in aluminum. Measures: 95" W x 72" H with a leg span of 24"
