(Sorry bout the bad quality of the photos, but for some reason I was really embarrassed of taking photos of vans and I was always trying to do it quickly and unnoticed :P And some of the best ones I didn't dare to photograph at all cos they were on such crowded streets... I should have just been proud of my hobby and concentrate a bit more!)
