As you might know, Shenzhen transforms itself almost by the minute.  This jumbo pack of 30 postcards, 30 “share” cards and what might be 460 small stickers was sourced in late 2023 and is still in its original cellowrap, so we don’t know what appears on the cards.  However we do know the reverse of the pack has a long description — Chinese only — telling of many of Shenzhen’s visual and gustatory attractions.  If you are looking for one comprehensive item showing Shenzhen up to that date, this would probably be it.  The scan of the front of the pack should give you some idea.  Grade: 1
