International Harvester Metro Step Van. I think of it as the art deco version of the Citroen H Van. This van is in amazing condition and I often see it in the neighborhood adjacent to the Kerby Ave. on ramp to go to work.
Finally got a chance to shoot it NW Portland. Take note of that fantastic wiper setup!
