Kindly get your coffee and relax because this description may take awhile.  It’s a set of four unused cards, each measuring 4″ x 11-5/8″, so they are well oversized.  The red paper wrap identifies this China Post product, from 2018, and our scan shows the front of one card (the other three are similar but with different places) and the reverse of another.  All cards have pre-printed, coloured postage and a kind of “shadow” graphic further identifying most of what’s on the front.  Clearly these cards fit many of our categories–in fact, they set the record–because Shenzhen is a city of about 15 million people and has everything, including Window of the World, a major theme park.  So, if you have any questions aboout these Shenzhen postcards, please ask us.  Grades: 1
