A friend recently came across this vintage Ford near San Jose, CA. After asking around it looks like about 50 of these Walker Evans special edition trucks were built by Dick Landfield for Ford to sell at dealerships in 1977. Walker Evans raced a Ford for part of 1977 before signing his deal with Dodge in 1978.
This 1977 Walker Evans edition Ford is restored and looks amazing. These photos are courtesy of the previous owner from their Flickr page. She said they sold it about a year ago to someone in Ohio.
