I'm pulling an old WFMW tip out of the archives to post today. I originally posted this last summer.
Most people have a place that is important to them--maybe a hometown, or the place they attended college, or a favorite vacation spot, etc. If you go to Ebay and do a search on "vintage postcards", plus the name of the location you have in mind, you might be surprised to see how large the selection is (and how cheap they are!). The vintage postcards often have a beautiful look--they're perfect for framing.
For example, when my brother and his wife moved back to the midwest from Philadelphia this past spring, as a housewarming gift I bought some vintage Philly postcards and framed them...voila! A very personal gift (and inexpensive too, but don't tell my brother!). Here's the finished project:
We lived in downtown Chicago early in our marriage, and I've begun a collection of vintage postcards showing various Chicago landmarks. When I have enough of them collected, I plan to frame them in matching frames and hang them in a large group.
