Aurora had closed shop. There were so many of the kits manufactured and they were so popular that it still wasn't difficult to obtain them all the way through the end of the 1970s. They were huge (1/13 scale), complex, and had piles of accessories. They were also snap-together, articulated, wildly-colored and possessed more of the nature of a toy playset to me than a fragile display model. Several have remained in production even today by successive owners of the kits' molds, and the giant Red Rex was recently reissued.
I've got a slideshow of photos of the exhibit I took when I set it up. Click HERE. Later, the museum's staff delicately spread it out into three cases. The exhibit was up for about 4 months.
The display had little informational display cards I wrote up, as well as copies of design illustrations by the late Dave Cockrum - famous comic artist and the designer of several of the kits, including the famous red Tyrannosaurus Rex. I also included a couple example of the Pyro/Life-Like dinosaur kits which were also contemporary to my original Aurora kit experiences.
