A carp leaping a falls stands for prosperity in Japan. In the case of this carp, it also looks very active but however if you look at the illustration closely, the carp tries to bite a feather jig dropped by a fisher because it is so hungry. I wish “he” would fail to bite it not to lose “his” life.
By checking the PDF (838 K byte) of the illustration, you can watch more detail of the feather jig.

Look forward to the next treasure hunting!
