This is an unopened set measuring 5-1/8″ x 7-3/8″ of 20 postcards.  The scan shows you the back of the cardboard cover (still in unsealed plastic film) and therefore we suppose those are thumbnail views of the cards inside.  The front of the cover (not shown) is a larger composite view of the Bund and a coy lady, along with some Chinese and English text.  Keeping in mind that “old” in Shanghai means “yesterday,” we remind you these are new cards with old views.  Grade: 1
