Purchase some artwork from a local talent. If you're on a tight budget, consider a print instead of original artwork; additionally, college art galleries can offer some unique bargains.
Along similar lines, photography is a tasteful reminder of a memorable destination. If you're not a shutterbug yourself, a nice framed photograph from a shop or gallery usually isn't too expensive; or you could buy a cool keepsake frame if you're taking photographs yourself.
A local bookstore will often sell local and regional titles that you won't find elsewhere, which can make for keepsakes that are both interesting and informative. A coffee table book of photos from a local photographer will last for decades and help you share the trip with others as well.
Think of things that are both functional and attractive. A Navajo blanket that you purchased in the Southwest, for example, will not only be useful, but serve as a frequent reminder of the place you obtained it.
Come up with your own category of collectibles that you always take home one of. Some people bring a tiny bottle of sand from their favorite beaches, for example, while others might obtain coins from their favorite countries.
A sturdy piece of clothing can be a stylish reminder of a particular destination as well. Cowboy boots from Wyoming, say, or a Mexican poncho, can last for years and will come in handy now and then too.
A bottle of wine or other potable local to a region makes a nice memento as well. What nicer way to really look back on that trip to Paris, for example, than uncorking a bottle of fine French wine years later and reflecting over a few glasses?
A living plant, that you can transplant back at home, can be a growing reminder of a great getaway. However, if you're undergoing interstate or international travel, you'll want to make sure the plant can legally be brought across state or national borders. Some states, such as California, have serious restrictions on this issue.
