Can you give us more info? That is a world class Clovis Point and so far all you have told is that it is from the Llano River in Texas and that you got it from a friend. Did he find it? What part of the river was it found in, what county, area?? How can you post a piece like this and not give all of the info with it?
Really Cool pics! Any chance you could contact your friend to get more info on it? Especially for your benefit since it will only add more value. Documentation is vital especially with a point like yours and there are lots of knowledgeable members on this site that will help with identifying finds but they also need a base to work off of. Hope your able to get more information!
