Are any of Mathew Brady's Civil War negatives in private hands? If so, how often do they appear on the market?

You can find MANY of his images in a high resolution format at the Library of Congress website.

These are public domain images, (unless othewise posted) and are free to use as you want.

Good question. Hopefully someone knows because I sure would like to.

Thanks for the memories. I wrote a term paper on him in college.
