©1971. 4x15.5x22.5" box contains white track sections, two controllers, transformer, four flag posts, guard rails and two snowmobiles. Box lid has litho pulls from wide tape across sides and 4" on top in two spots. Box is just Good. Comes with partial instructions and partial flag sheet. Snowmobiles were tested and do run on track with controllers. Missing some front trim pieces on one and skis loose but stay in place when running. Contents are VF overall. An interesting twist on slot car tracks.
