Jeon Hyeong-pil
From the early 1930s, while Korea was under Japanese rule, Jeon Hyeong-pil spent much of a large inherited fortune on Korean paintings, ceramics and calligraphy. Among the things he kept was the copy of the Hunminjeongeum Haerye, the 1446 book that explains the Korean alphabet, found in Andong in 1940 and now a National Treasure of Korea. Keeping for decades what a whole country would later name a national treasure shows the shape from outside.
