What's the best place on a book for an autograph?

[Jimmy C]

I've secured a chance to get a manga volume I own autographed by its artist, I would like some suggestions on where's the best place on the book for it.

Outer jacket?
Frontispiece (the page before the ToC, usually has art)?
A regular page in the book?
The inner cover?

I'm not too keen on the jacket. It can be removed and I would prefer the signature on the book itself.
So, I'm leaning to either the frontispiece or the last page of the volume, where there's a Thank You message from the artist.

So, any suggestions?
