There are a number of stories of lost & found cameras on Craigslist.com. I created a list of cities on the left side (scroll down) with links to "lost & found cameras." While people describe the cameras (most are digital), many are more interested in getting the memory card back.
"lost my digital camera around the 15th of january if you found a kodak silver camera please let me know it has a memory card in it and i would really apreciate it if i could get it back please"
"Lost Olympus camera in Atlanta airport. Contains 500 pictures from vacation in Italy. Would just like the memory card back, please. Reward offered.."
"If stolen, please return SD card (have a heart)"
Some describe the photos on the camera for identity purposes:
"You can tell its mine when you look at all the saved photos, there will be tons and tons of pictures of tarantulas, scorpions and so on."
