I have located some photos (8) taken by my 2nd Great Grand Uncle, Noah D. Davis, on a website for the Penn State University, Historical Collections and Labor Archives, William C. Darrah Collection of Cartes-de-visite 1860-1900. Only one photo had a persons name on it (Wright Kidder) but all were taken at the studio in Geneseo, Illinois. This collection of photographs is huge (not just Illinois!) and all the pictures can be ordered for a reasonable fee. The link will take you to a page to search by photographer or geographical area.
