Look each week on the front page of your Our Towns section for a piece of the "mystery photo." For four weeks we will publish a different piece of the picture in each of the four zones. To score the 1,000 points, players must collect all 16 pieces of the picture and guess what the image is.

We've included a map of Our Towns zones on this page. To complete the picture, you will need pick up copies of Our Towns from the other zones or meet players in other zones in the forums.

After you collect all 16 pieces, attach them to a piece of paper or cardboard and mail them to the Democrat and Chronicle. We will accept newsprint copies only. No photo copies. Put your name and PTI username, and the names of up to three other collaborators, on the back. Send them to: Democrat and Chronicle, Photo Department, 55 Exchange Blvd., Rochester, NY, 14621. Make sure to identify the mystery photo, which is an invention very important to Rochester. Entries must be delivered or postmarked by Oct. 9.
