These are quite “busy” unused cards, front and back.  You can see most of one of the 16 through the cut-out window in the cardboard cover shown in our scan.  They have heavily serrated edges, and each card has extensive text.  On the front, it identifies the scene — all around the Shangri-La area.  On the back, it’s a kind of dreamy, romantic ode.  We’ve not tried the QR codes on the reverse!  Grade: 1
