Marx Streamline Speedway Toy Race Car Set Tin Ltiho w/Key Racecar. The box is 95% there just need to be carefully brought back together. The cars have their original boxes as well as the inserts to divide the track. There is one tab broken off the bridge where they connect. They will still fit together because the other tab is there. I do not have a key to test the cars but they are real nice shape. This is early plastic like Bakelite. Very cool piece to have.
