Consider the case of the Linda McCartney's Home Cooking, signed to Kim Basinger and Alec Baldwin. Not only does this copy have a warm personal inscription, it contains an authorial drawing as well. It is a pictograph of a fish crossed out by an "x," obviously a suggestion from McCartney that the recipients might consider switching from a pesco-vegetarian diet to an entirely vegetarian one.
In 1993, I hosted [Saturday Night Live] when Paul McCartney was performing, and I met the warm and down to earth Linda McCartney backstage. We briefly talked about her animal rights work, since I had been introduced to the issue while living with Kim.
