James will be delighted to see you reading one of his books in public. When he does, James will introduce himself and ask if he can take a photo. If you then agree, James will publish it on this web site.*
While at it, if there is a pen at hand, James will be pleased to sign the book that you are reading at the time.
As more of a challenge - if you are reading one of James' books on Kindle and you recognise James as he travels about, he will also be thrilled to take your photo and publish it.* Of course, he will only do so if you want. Signing a Kindle would, however, be more challenging!
* How long your photo will be published for will be at James' discretion, or until you ask for it to be removed.
