This car on display at USA of Yesterday Motors at 455 St. Helens, Tacoma, is one of 500 remaining Amphicars left in existence. The informational sign said that these amphibious cars are capable of crossing between England and France!
The USA of Yesterday building was constructed in 1948 and contains 61,000 square feet of space. It was originally known as the Mueller-Harkins Motor Co. Building and Silas E. Nelsen was the architect. It was a Buick Dealership. It is now U.S.A. of Yesterday Motor Car Co. (see the link below) and besides showroom space has a large banquet room in the style of the 1950s. In 2007 there was talk of demolishing the property to make way for a downtown grocery store, but that didn’t happen.
A picture of the building from 1950 can be found at Tacoma Public Library http://search.tacomapubliclibrary.org/buildings/bldg1image.asp?j=2&o=2&n=24408&i=8170#text
