Hangul Day Exists Because a Book Turned Up in 1940. Nobody Can Find the Other Copy.
The date of Korea's alphabet holiday moved four times before a single physical book settled it — and that book arrived missing its first four pages, including King Sejong's own preface, which a calligrapher reconstructed by hand with a typo still in it. A second copy has been in a private house since 2008. The prosecution's own appraisers valued it at over a trillion won. Nobody has seen it since a fire in 2015.
