It is not common here either....
But as a teacher, I would suggest a book for the class/school library about your location!
It is always fun to have books that have personal ties to them, they get a lot of use in the classroom and are popular. We had a student leave school for a week and did a Civil War (Virgina & down south) tour with his family. He brought back a wonderful book on 'Civil War' mysteries (legends, tall tales, haunted houses, unexplained mysteries...) that was VERY popular with the 5th grade. Another student visited India and brought back a beautiful coffee table book of photos. Very pretty, it also got a lot of use---as well as opened a lot of discussion with the student about India. We also had a students another year share a book on caves after visiting Mammoth Cave.
The exception would be if you went to an amusement park or something, then I would likely suggest nothing--or maybe a postcard. Although some of the Amusement parks even have some interesting books on the history/photos (make great writing prompts).
If you travel to another state/region/country/neat location I would try to find a nice age appropriate book (desert animals if you went to Arizona, European castles if you went to Europe, etc). It is not hard to find books on local history, animals, culture, etc
