Koichi Yamamoto uses etching and color aquatint to create this organic image, an ancient stump that rises and grows into an intricate structure, an octagonal fortress of stone and a web-like "neural structure" moving through and around it.
The artist added a tonal aquatint to add a subtle, evolving color, somewhat like the Japanese woodblock printing method of 'bokashi', a variation in lightness and darkness (value) of color by hand applying a gradation of ink to a matrix.
This etching is dedicated "for Gordon", a gift to Portland, Oregon artist, and curator Gordon Gilkey. This impression was deaccessioned as a duplicate from the Vivian and Gordon Gilkey Graphics Art Collection at the Portland Museum of Art, which has a collection of Yamamoto's work.
