Type... Game Touken Ranbu Toudan Mutsunokami Yoshiyuki This is a postcard that was sold at the special exhibition "150 Years After Death: Sakamoto Ryoma" held at the Edo-Tokyo Museum from April 29th to June 18th, 2017? (My memory is vague, so I don't remember if I bought it or if it was a bonus.) I have kept it for many years, but I think it is in good condition. Instant purchase is welcome.
