This is a very old O-Henro (Shikoku Pilgrimage) stamp book. One book appears to be from Meiji 21 (probably 21st year), but the other is in poor condition and completely unreadable, so please consider it a bonus. The contents are barely visible. I believe they are about 130 years old. They were stored together with an image of Kobo Daishi. How about it, collectors?
