Freibeit Frichert? edited to Frieheit
The photographer was Lucius M. Schofield in Spring Valley Minn. I found the photographer there during the years 1889 to 1894.
Update from Iggy:
The 1880 US Census lists John G. Frieheit (b. abt 1830 in Prussia), living in Fillmore, MN which is 10 miles from Spring Valley, MN.
John G. Frieheit had a son named Henry (b. 1874), and he in turn had a son named John Freiheit (b. 1899) that lived in Spring Valley proper (in 1930).
