This is a series of boarding tickets featuring the various train types of the Omi Railway. Only five books from Series 3 to Series 7 are available. Unfortunately, I couldn't find Series 1 and 2 despite searching. These were issued from 1973 to 1974. You can also see information on Taisho-era trains and Meiji-era timetables. I'm selling all five books together. Thank you.
