The June, 1990 Reflector also has a picture of Gen'l Lytle on page 38. The Reflector has no picture of the Gen'l Buell other than that half of her shows in this view. The Steamboat Photo Company list (Way's Directory, 1950 edition) does not list General Buell. The only chances to find one are in Dale's dusty boxes or the Murphy Library.
That half-view indicates that the two generals were very much alike.
