Facebook page posted this photo of Josiah Marvel of Hendricks County, with the following information:
"Meet Union soldier and Hendricks County boy Josiah Marvel. Although only 15 years old, Marvel enlisted in the Seventh Regiment Indiana Volunteers in 1861. At the time, enlarging photographs was tedious work, and specialists reproduced and enhanced them with a crayon to increase contrast and hide blemishes. This portrait is a beautiful example of this early, but complicated, photographic process."
