It’s roughly two years since I started to visit galleries on every Saturday and I’ve probably visited more than 500 exhibitions of calligraphy. I usually visit few places in Ginza, sometimes in Ueno and occasionally in Roppongi. Luckily all of them are always entrance free and I need to pay only for transportation. Calligraphy is a hobby for retirement and probably most of visitors don’t have an email address. It sounds very old school, but these post cards are still used to invite people. I scanned few to show them to you. Would you say that these are invitation cards for exhibitions of calligraphy?
