gift ideas

I wanted to get my latin teacher of four years a nice but inexpensive book as a gift to thank her for writing me a letter of recommendation. Any suggestions?

I suppose she's got Harrius Potter et Philosophi Lapis?

The little Loeb classics are nice volumes. They are affordable on Amazon and would be appreciated by any classics scholar. The green volumes are Ancient Greek/English, and the red volumes are the Latin/English translations.

Good luck in getting the perfect gift.
