You are bidding on an American flyer number 577 billboard whistle. This whistle was produced on July 7 1947. The billboard is in great condition, the colors are vibrant. The frame and stand are in good shape. On the top behind the billboard there is a few dots of black paint. The whistle worked when tested. It comes in its original box with its original paperwork which includes the inspectors voucher and operating instructions. The billboard also comes with the original button. The box is in excellent shape. All flaps are present and the logo is clear and legible. If you have any questions feel free to message me. Good Luck Bidding.
