It is a small whilte notebook, 14 x 9cm in dimension, with photo pages at the front and back and ruled and blank pages through the centre. The lining inside the cover is purple, as is the bookmark ribbon and the lines and text on each of the pages for writing, which also feature Koyama's name.
Sharing here the photo pages from the notebook, which were organised in 2 discrete sets starting from both covers, which both have Koyama's name on them. Another very nice keepsake.
