Sambo in Seoul

The Itaewon Global Village Festival is happening soon, and from the banners that have been put up along my daily walk to the subway, I see that Little Black Sambo will be part of the celebration. Furthering my theory that you aren't anything in Korea unless you have a ridiculous cartoon mascot, at least the organizers seem to have equally embraced other racial caricatures. Any guesses who the other two are supposed to represent?
