I was fortunate enough (but nearly missed the boat!) to be able to buy these original Bob Marrion watercolours recently. Charles S Grant was selling them off on behalf of Bob's widow, so given that this was probably a unique opportunity I bought these four at a very reasonable price.
Confederate States Marines 1863
2nd Wisconsin, Bull Run 1861
Major, 33rd Virginia, Manassas 1861 (Northern-style rank insignia)
Private, 33rd Virginia, Manassas 1861
I think everyone would agree that these are beautiful and I feel very fortunate to be able to hang them in my house.
