Mental Radio

World reknowned author and catylst for social change, Upton Sinclair, surprised the public with this book in 1929... written after three years of intensive study of all available scientific psychic research, and after conducting hundreds of hands-on experiments with the aid of his associates, and his wife, Mary Craig Kimbrough.

Known as "Craig" to her friends, Mrs. Sinclair had shown a life long telepathic and psychic ability, which fascinated her husband, who decided they could conduct their own scientifically controlled studies of the phenomenon. Illustrated with more than 145 pictures produced during their experiments, this book is guaranteed to fascinate, and make you think a little more deeply about the possibilities of the human mind.
