It is odd for Hongkong Post to issue something like this, but they did, so we will describe what we have.  They are books of postcards, bound into a softcover sets of which you see the cover here.  The whole thing measures 5-1/2″ x 9-1/2″ x about 1/4″ and is heavy.  Of the 17 pages in each set, 16 are postcards (in the similar style as this photo) and one is a sort of introductory page of the same size, but not a postcard.  Hope that’s clear.  These are odd.  Special postage rate will apply:  please ask us.  Grade: 1
