I'm not going to vouch for the authenticity of this item, but the seller of this copy of "The Art of the Theremin" claims it is signed "TO ANWA & YEHUD LOVE CLARA". As always, do your own research and beware of scams. If this is authentic, I imagine it's probably worth much more than the current bid price of roughly $35 USD.
