I was given this 30x24 musuem framed print a few years ago by a past friend of the family. This person gave to me due to my interest in the civil war, they were downsizing greatly and no longer wished to have it. The only history I have is that it was purchased many years ago at an estate sale. I have zero clue on the authenticity or perhaps the value, and would be greatly appreciative for any insight. There is a small tear on the protective paper backing on the rear of the frame. Otherwise no other blemishes. The art gallery that framed it appears to still be in business. I researched that particular 1862 publishing of the Harper's Weekly and this was a large two page print, that explains the crease in the middle of the actual print that is framed. It's titled in the 1862 weekly - "The War for the Union, A Cavalry Charge". Thanks in advance for anyone's insight.
