This set of 12 unused cards is distinctive and nicely done.  It has nothing to do with hot dogs.  It’s a set of 12 cards of old Hong Kong busses in a variety of settings:  urban, rural, on the road, being inspected, etc.  Captions are all in Chinese.  The set is wrapped in heavy cardboard, and our scan shows the cover (which closes using a string tie similar to a mailing envelope) and one of the 12 cards.  Grade: 1
