This is one of a massive packet of photos bought from ebay and well worth it. I was initially drawn to his pointed mustache, the type that tempts a mans fingers to twirl the ends. After examining the photo, I have come to realize that this is likely a collodion print because the colors are so very rich and clear. The collodion process is more like our modern film technology, and resulted in crisp images. Prints also sometimes have a lavender, purple or deep blue shade to them. The collodion process was popular in America after 1894, so that is the date I am using. However, this CdV features text in what I think is Swedish. Perhaps one of you can confirm this for me.
