This is a Cabinet Card from the Antique Mall in Detroit Lakes Minnesota.
Oleson is the photographer at 226 & 228 Washington Ave S Minneapolis, Minn. He was at that address from 1880 to 1881, John Oleson died in 1881, his wife took over his photo studio.
This is the Swenson/Swanson family. Children: John, Martha and Marshall. Their parents are John and Gertrude.
Thanks for stopping by.
I will guess that this photo was taken about 1885 or 1886 from the birth dates of the children.
