Philatelic set measuring 7-5/8″ x 11″ in its cardboard cover, with a First Day cover and two sets of four related stamps facing.  One fold-out page only has a plain gold panel.  We don’t know if something was supposed to be inside that or not, but it wasn’t there when we got this from the post office in Shenzhen.  Issued by China National Philatelic Corporation in 2019.  Grade: 1
