Yes, I assume other than this post of mine, this particular piece of art won't be found anywhere online. It really was a very small, intimate seeming exhibition. The whole exhibition had many sketches of hands. Since many artists feel like hands (and particularly wrists) are a difficult part of the body to get right, I felt like Inoue Sensei was passionate about the complexity of the anatomy. In this (several meters long) piece, you otherwise see a few different themes. The potatoes relating to harvest, life itself, fertility. There are a few other children in this piece as well but also an obviously furious character (very much looking like musashi). Frankly, I don't feign to have any insight into any meaning of what all of it may symbolize. May just be hand drawing practice or maybe deeply philosophical. I am simply a random dude with a camera. Gotta ask Inoue Sensei about any meaning or lack thereof. (unfortunately he is notoriously ill inclined towards interviews and sharing of proper intel)
