Dealer Display ???

[68l30]

I'm wondering if anyone can help date the following dealer display pieces.I purchased the items from a old dealer that was closed during past year.I feel both pieces are from the late 60's early 70's but would like to narrow it down a bit more.

The first case was wall mounted and is backlit with several glass shelves.The center section opens for advertising slogans,prices, or whatever you wanted to put in there.Units are made of fiberglass,aluminum,and glass with locking doors ...I also have a unit that is two sided and free standing.Same overall design.....but not wall mounted like the others.

The next piece is a display rack for the dealer brochures and other dealer lit. It is labled Chevrolet Information Center.This one is made of wood and aluminum..It does have a DOT transportation lable/sticker on the bottom edge but it is not dated.

I have checked all my dealer info and can't find any good pic's of these units...Anyone remember them? Thanks...
