Talk About Digging Things Up!

The club has recently come across old newsletters. We are in the process of digitizing them for posterity's sake. I thought it would be great to post the very first newsletter of our club here for all to see. This newsletter was originally mimeographed (remember the smell of mimeographed pages!) and later zeroxed. With some time and effort, it was scanned in and cleaned up. Click here to see what was going on in the club in October of 1946.
