We shamefully admit our research resources sometimes vanish while we enter cards, and this is one such case.  If you read Chinese, there’s an extensive story on the back cover of the set, to explain everything.  We have two similar but not identical sets available (see also our entry 20307809), with one focusing on “chops” and the other on art and calligraphy.  Scan #20307808 shows the front of the cover (lower left) and two sample cards from the set of 10–all unused.  Scan #20307809 does the same for the other set.  Cost is per set.  Take both for $20.  Grades: 1
