Sketch of GMC Truck exhibit

Here is a 35mm slide I still have of a sketch prepared for my Dad's client, GMC Truck and Coach Division by Exhibitgroup Chicago. It is meant to give a view of the way the exhibit would look for the 1980 displays being built and configured for that year's upcoming shows.

There are very nice full-size GMC trucks of several types that were going to be placed among the displays. At least one shown here is a giant "The General" semi-truck that attendees could view. The full exhibit would be much larger than just this view shows.
