Just an awesome technic parts pack.

The two Universal Joints included made my day when I was gifted with this. Not much choice for color though, just yellow beams and plates.

The box also contains suggestions on how to build a small winch device with the parts, as well as some other minor constructions.

You gotta love early technic boxes, even the parts pack had an opening top lid with a clear window showing the parts inside! Sturdy too, still surviving to the present.
