This is a set of two books from the Earth Music Library series, "Takuro Yoshida" (published in 1996, 2nd printing, and 2007, revised and enlarged edition, 1st printing). Both books were supervised by Hideki Taya, written by Hideki Taya, Takehiko Suga, Ken Ikeda, and Hiromasa Murano, with artist photos by Hitoshi Tamura, and published by TOKYO FM Publishing. I purchased these for preservation, so I haven't flipped through the pages, and there are no markings or writings. However, they have been stored on a bookshelf for a long time, so there is some soiling and discoloration on the covers. Please understand that these are old books before purchasing. For reference, I have uploaded photos of the table of contents, but these were taken from a different, read copy of the book, not the ones being sold.
