Map of Korea (1800s?)---米国の図書館保管
韓国が主張する独島の旧名称(于山島)とウルルン島(鬱陵島)の地図。(于山島は1つの島からなっているが、竹島は2つの島からなる。)
The map showed Ulleungdo (鬱陵島 - 울릉도) with a neighboring island labeled as "Udo" (于島 - 우도), which was probably a shortened form of "Usando" (于山島 - 우산도). The map was titled "The Famous Map of 'Joseon Yeojido'" (有明朝鮮輿地圖) and is stored in the US Library of Congress.
