Is this Abraham Lincoln?

I believe Lincoln and the man in the photograph are two different people.

Lincoln didn't start growing his beard until the 1860 Presidential election after receiving a letter from an 11 year-old girl named Grace Bedell urging him to grow a beard. So, if the man was Lincoln, the photo couldn't have been taken prior to 1860. There are many different photos of Lincoln from the 1860's and I don't think the man in this photo resembles the known photos of Lincoln from this time period.
