1970s Hot Wheels Jumpmasters Adjustable Jump Set, complete with original box, track pieces, cardboard building structures, 4-speed power booster, and one red die-cast car. The Jumpmasters line was a short-lived stunt play system from Mattel, making complete sets with original packaging harder to find than standard track sets from the same era. A solid find for Hot Wheels collectors focused on vintage stunt and accessory sets from the 1970s. Set is gently used with minor play wear throughout. The original box has edge damage and surface wear. Track pieces and components are present and intact. One-owner. Please feel free to contact us with questions.
