Sometimes a seemingly plain postcard masks an extraordinarily colourful story.  We often refer to information from Wikipedia (and why didn’t we have Wikipedia when we were in school?), but almost never direct you to the entire entry as we are doing now:  https://en.wikipedia.org/wiki/Kinkaku-ji.  We aren’t certain when this unused old B&W postcard was produced — we’re guessing 1960s but don’t know — though the extensive Japanese caption on the reverse might tell you more.  Grade: 1
