In the collection there is a CDV (by Winder’s Sky-Light Gallery of Cincinnati) copy of a tintype of an artillery piece in the Library of Congress' Liljenquist Family Collection which is said to be a mountain howitzer of the 5th Ohio Cavalry Company: http://www.loc.gov/pictures/item/2013645732/
That's a lovely collection, thanks for posting the link! The Judd family photo is the only one I'd come across before- the rest brand, new looks at the war. They're all wonderful.
I must say I dont think I have ever seen photographs quite like this with such a personal touch in almost every one of them. This Photographer truly had an artistic bent when he made these.
The one with the plate of food is really something.
