Backyard Archeology

After many months of resuscitating an old garden behind our house and up ending old fence posts to start building a playhouse, my husband and his trusty team of archaeologist trainees have uncovered some interesting finds. My daughter reported that  "they are from the 1920s, I scanned them into the computer and it told me."  Regardless of their origin or heritage, they sure start the kids wondering, how did they get there? who lived here before us? what did our neighbourhood look like back then?
