If a picture is worth 1000 words, how much is a filmstrip good for? Well, in this case, it’s worth a copy of vintage CERA Bulletin 97, published in 1953, about the electric railways of Wisconsin. You can win it in our Mystery Filmstrip Contest.

Here’s how to play:

In this post, we are publishing all the printable images from a single roll of Kodak Super XX film taken decades ago on someone’s trip to Chicago. Taken together, these pictures contain clues about when and where these pictures were taken. All the information we’re giving you is the frame numbers and the images themselves.

Try to guess the date, or a range of dates, when these pictures may have been taken, and also try to identify the locations of as many of the images as you can. Submit your answer in writing no later than midnight Chicago time on Tuesday, May 7, 2013- one week from the date of this post. We will pick a winner based on best overall performance.

Send your contest entries to: cerablog1@gmail.com

The lucky winner will be announced on Wednesday, May 8th. We will send the winner their prize by mail.

Good luck!
