Does anyone have any idea who and how to contact someone who can authenticate, and identify possible date and area of origin for Native artifacts? I have been writing to Universities asking for help for many years and have yet to receive anything back from them showing any interest in even looking at my photos. My father claimed to have found them about 1933 and they are remarkable. He passed them on to me with little explanation of how he came to have them but he said he got them at the age of 16 one summer when his father ordered him to working on a distant relative's farm to "build character."
