The cover says "Toyama Collection." I believe this person compiled a year's worth of material into a book. January, February, and March of Showa 21 (1946) - 3 volumes, with some tearing in one. May - 2 volumes, June - 3 volumes, July - 3 volumes, August - 3 volumes, September - 3 volumes, October - 3 volumes, November - 3 volumes, December - 2 volumes. Also included is another book, an English book titled "SAKURA."
