We often refer to “innovative products from China Post,” and this is one of them.  We almost need a YouTube video to describe it.  First, it’s “IOC Authorized Product of London 2012” Olympics.  Now, as you see the photo, imagine lifting up the string and unfolding the red cover to reveal four attached postcard cartoon-type drawings of London landmarks, each with a PRC stamp affixed.  Then there is a page of four extra stickers that children “should be guided by adults” to place on the cards; and, finally, one more page with a mint British stamp.     Definitely one of a kind.  Unused.  Grade: 1
