That is a neat photo of the frame.

It looks like it's on a dynamo, or the rear wheel looks like it.

I can't read the plaques on the trophies very well, one looks like is says Packard Four Hundred.
What were they for?
Are the trophies still around?

It looks like there is a stripe or line on the long bar, I assume to show the twist when the system is working?

There is something printed on the box behind the two men, I can not make out what it says.

Here is the 55 frame at an auto show.https://packardinfo.com/xoops/html/uploads/photos/101.jpg

Would this have been what was shown with the frame display?https://www.youtube.com/watch?v=8Sz0RZUySk0&app=desktop[/quote]

No idea what happened to the trophies but they were displayed for a time in the factory showroom in the plant on East Grand Blvd. I believe the trophies were awarded in New York at the successor show to the International Motor Sport Show (see the Pan American story in The Packard Cormorant magazine). Which also begs the bigger question of what happened to the huge trophy that was awarded to the Pan American?

Note that the 1955 display chassis had at least two incarnations:
1.) Black air cleaner and other details with pre-1955 wheel covers with cloisonne centers
2.) Chromed air cleaner and other details with 1955 wheel covers

The chassis was re-vamped again for 1956 and push-button shift was included with full aluminum housing Ultramatic transmission and other detail changes.

The movie short here was keyed toward sales personnel, but the one used at auto shows was geared toward customers/buyers and had a different producer as I recall.
