Tamami Shima 1961 Print (Unnumbered)

I can't wait to put this on my wall! I found it rolled up in an estate sale closet for $15. I found a Donald Judd "Aquatint" a couple years ago the same way for $3. Anyway, it has some condition issues on the edges from tape, but I couldn't care less. The piece is signed twice, titled in Japanese and is not numbered. Any information anyone can provide would be most appreciated.
