This was the third box I scanned. These are generally much earlier than the other two boxes; they appear to precede the married couples seen in the previous boxes. The people seen in the other 'albums' appear to be teen-agers, of the same era and earlier as the 'troublemaker' photos in the Red Album. The negatives, including across albums, appear to be in reverse chronological order.
Also, appearing in these photos is Revere, Minnesota, a small town in west-southwest Minnesota, around 50 to 100 miles southeast of where the later photos originate.
