Last week, I realized that the four artist's book editions that I completed this past winter were representative of the four elements: earth (Natural Philosophies), air (Amissa Anima), fire (Family Style), and water (Between, Among, Within). I wish I could say that I planned things that way.
Nope. The subconscious mind is the only part of me that can take credit.
However, the active mind has created several venues for purchase, in case you weren't at Codex.
