Oh man won

Up until about a week ago, the Korean bill of the highest denomination was the man won (10,000w), which is worth about 9$ Canadian. This was annoying if you were going on holiday or had to take out a large amount of cash for any other reason - you were left with massive bank-job bricks of green that you had to lug around in a hyperinflation gunny sack.
Last week Korea issued the oh man won (50,000w) bill, or about 45$. I like half of it. The front features Shin Sa Im Tang, the first woman pictured on Korean currency. Not overly sure who she is, but apparently she was an artist, and she gave birth to the dude on the 1,000w note. The back side is terrible. A dead tree? Boooo.
