In this case, Freda wrote down the wife's name which is obviously very helpful now, 100 years later when working on these old photos.

Herman & Tina (Kruse) Arp
T.A. Berhalter studio, Preston, Iowa
Another important aspect of preserving history is to document the name of the studio and any other information that might be on the front or back of the photo.

Hopefully this is the correct Tina Kruse because I didn't find any Manning connections at this point:
