An Ebay purchase from Spokane, Washington. This McManus Brothers studio carte de visite has the negative number 1077 on its back, suggesting it is a fairly early photo.

Currently I have seven of these carte de visite with negative numbers. No. 185 is from Alphonso McManus. According to the Directory of Early Michigan Photographs, he began working in Traverse City in 1868.

His brother reportedly joined him in 1873, but I suspect that it was a little earlier. No. 451 is from the McManus Brothers. No. 1017, 1077, 1354, 1404, and 1759 all have the same McManus Brothers mark on the back. 

No. 1017, Daniel Matteson, is dated 1873, revealing those before that date prior to 1873, and those afterward (except perhaps No. 1077) to date to after 1873.
