This is a CdV or Cartes de visite similar in size to our wallet photographs today.
I purchased this photo at the antique shop in Bemidji Minnesota.
Here we have the price, Best Photographs $2.00 per doz.
W.L. Barnes was in Winona Minnesota from 1866 to 1892. He was at Center Street from 1886 to 1892. Based on the woman’s dress I will say this photo was taken in 1886 if not a tad earlier. Rows of buttons, pleated decorations on the skirt and a high white collar all say 1880’s.
Thanks for stopping by, do come again:)
