The above link contains great vintage pictures of the early days of TKD & one of its Pioneers, GM CK Choi. He was the 1st Korean National Heavy Weight Champion. He toured the world teaching, promoting & helping to develop TKD. The website also contains historical information on the above.

There is also a link for his new book on the Timeline History & Original TKD Self Defense techniques. At $20USD, it seems like a good deal. Posted for your consideration.
