Here’s the address at which you can contact Kate.  If you live in UK send a properly stamped and self addressed envelope (minimum size 8.5″ x 4″) with your request letter and a photo. You can include a piece of cardboard to keep the photo from bending in shipping and also add “Do Not Bend” on the envelopes. Send your letter and wait. On average, there is going to be a 3+ month wait for a response. If you do not live in UK, add several* International Reply Coupons. The International Reply Coupons (IRC) will be used by the receiver to purchase english stamps. You can only get them at your post office. Place the IRCs into the envelope, not on it.
