I think 1979 was probably the first year I subscribed to Car Craft (too many custom vans in Hot Rod...). I remember that image on Van Nuys Blvd vividly. Such a cool and unique car/paint scheme. And now we know its owner was pretty unique, too.
I predict it was purchased by someone who knew of its media significance, and has hidden it away for all these years. It will eventually emerge covered in dust, on a YouTube special, from some mid-south barn.
