From the "files" of www.BlufftonForever.com, a story on some 30 years of Bluffton photographic history:

Most residents 65 and older once sat in the chair where this photo was taken. It was taken in 1971 in the Leland Gerber Photography Studio. The studio is now part of the parking lot of Citizens National Bank (north of the Post Office). 

Between the mid-1950s to early 1980s, Gerber took most of Bluffton High School's senior portraits, community weddings, anniversary photos and everything else. The story is posted on https://www.blufftonforever.com/post/he-took-your-senior-picture.
