Set is in nice vintage shape. It has been used and shows signs of wear and age. I counted 29 pieces of track all of which are numbered with what appears to be chalk.
One piece of track had a little rust and a small crack. Aside from that I didn't see any other cracked track.
From what I can tell it looks to be complete. The black cars body is loose from its chassis, but aside from that I didn't see any damage to the cars. Pieces do show normal wear such as scratches and scuffs. This set has not been tested.
The box shows some wear and age. It has some small tears and a lot of scuffing/creasing. The directions are on the reverse side of the box as shown in pictures. See pictures to make your own determination on physical condition and completeness.
