Sent to her private address, which can be googled in several sources
Sad to receive RTS, I've mailed the same lor, pics and sase to the address in the database - let's see what happens.
I sent to her address in the database on March 5th and didn't receive a RTS yet. Many celebrities apparently dislike answering mail at their actual home address and use a company or a P.O. box. I tried what you did and sent to one of Steven Seagal's homes and got a RTS. Also, Vincent Pastore who played Big Pussy in the Sopranos lives near me and I know that he only accepts fan mail at his P.O. box and sends mail back that is addressed to his house. Good luck.
You may be in for a long wait, just letting you know. Yoko is a busy woman and her secretary is a bit of a....well...it seems she "takes her time"...I sent to Yoko two years ago..ever heard back. Sent to her in July 2013...didn't hear back until Jan. 2014! Well worth it. She is a great addition to any collection. So eve if you have to wait...that is what its all about!
