These are pictures of two South Korean flags in my Korean War collection. I have to admit that Korean War items are very few and far between. I have a couple of North Korean flags that I will post when I have time. I will give all this advice, quality Korean War items are sleepers on the collecting market right now. Whenever I find a quality Korean War piece (US or otherwise), I try to pick it up. I paid $20 a piece for these flags at local militaria shows. First flag is made of cotton.
