Spotted this vintage International Harvester Metro Van while driving around town last weekend. Not sure of the year, but I'd guess late 1940s/early 1950s. Metros were a line of delivery vans manufactured by International Harvester between 1938 and 1984. The streamlining of the early models (like this one) is pretty great.
I think this van is now used mainly as a mobile billboard, but those elegant lines still shine through.
