This is a set of ten cards with artistic renditions of sporting stadiums and venues for the summer games.  Each card is like a Maximum Card by having a stamp from the games on the front, but the stamp is the same on each card and has the cartoon mascot.  Next to the stamp is a small actual photo of the larger artwork on the front of each card.  There is no postage pre-printed on the reverse, but details of the designer, engraver, authorizations, etc.  All of these are packed in a very hard and thick cardboard box, which is what you see in the scan.  An attached ribbon helps open the lid.  This is very durable; the reverse of the cover explains the games and these “engraving postcards” in Chinese and English, and also has a holographic sticker vouching for authenticity.  That’s all we can say!   Grade: 1
