Gift ideas for a Mentor

I am in the Master's in Counseling program and I have had a fantastic experience with my Supervisor. He has helped my professional growth as a budding counselor in so many ways. I am eager to hear of ideas for a gift for him for his interest and contribution to my growth that will be meaningful.
Has anyone heard of, given, or received a particularly meaningful gift that expresses gratitude that you'd like to share?
His gift to me was a small stuffed panda that accompanied a list of characteristics related to the panda that he admired about me.
Thanks -
I have a few ideas and always admire the creativity and thought of the women on this board.

How about a small book or children's book or something that best describes his quality you find most helpful to you?

One of my favorite teachers once gave me a copy of The Little Prince with an inscription--but I still don't know exactly what she meant! (I should re-read.)

That is a great idea :)

The Spyglass by Richard Paul Evans, about faith and believing in impossible things.

The Little Prince is good for just about anyone, except for people who need the Encyclopedia of Immaturity.
