The tail of Karl Gratz's Bf109G does have an earlier known photo and artwork in Jagdwaffe Luftwaffe Colours, The War in Russia 1942 Vol.3 Section 4 page 374 with 83 Victories with 8/JG52.
The Pic in Lif 28 is a latter image showing the same rudder with 87 Victories with 11/JG 2 don't recall seeing it anywhere else.
Sure Jim will likely forward you an image of the page....
