These were published in 1958 and issued in two sets and I own both of them; I don't remember where I got them, probably on vacation in 1961 or 1964. There was a Union set of four prints: this one, 1863 6th Penn. Cav. fighting dismounted; an 1862 group of Wisconsin soldiers beside a campfire; and a mounted captain of artillery in a snowy 1864 road scene. The Confederate set included a mounted 1864 group of Terry's Texas Rangers; an 1862 cannoneer of the 5th (western) company of the N. O. Washington Artillery; an 1863 campfire group of infantry; and a dismounted officer of the 1st Va. Cav. in 1861. Tom Parker was the artist and I really haven't found any inaccuracies in any of these, which I have had framed on my walls for literally decades and look at every day!
