This came out of my parents' bookshelf. It seems my grandfather, who loved mountains, bought it at an exhibition by Tsugio Katano a long time ago. It's a collection of photographs, but not a book; each photo is separate, and they are almost A4 size. I just looked through it, and although the case shows some discoloration, the inside is quite clean for something so old. I think it was probably looked at a little after it was purchased and then put away. (This is just my subjective opinion, so please check the images) As it may be a valuable collection of works now, I'm offering it to someone who appreciates it. Free shipping. Mountaineering fans, please take a look.
