Here is an unidentified CDV of a Union Army infantry officer. His kepi has an infantry hunting horn (number illegible) with a 3rd Corps Badge sewn on the top. A very handsome and dashing gentleman, indeed! Photo was taken at the famous Root's Gallery at the corner of 5th & Chestnut, across from Independence Hall and the Liberty Bell. Condition: Image is clear and crisp.
