The source of this pic describes it as a 54 Corvette Nomad.

It also goes on to say:

"1954 Corvette Nomad Wagon Concept. Chevy developed a series of concept vehicles based on the new Corvette. Unfortunately (or fortunately, depending on your viewpoint), the Corvette part of the equation never materialized. Of course, Chevy did release the Nomad the following year under the the Belair line. As far as I know, this is the only one ever made by Chevy."

Our neighbors had a Nomad, which was just the same as our station wagon except with even more chrome.
