“Aerojet-General Corporation artist’s concept shows how the Apollo spacecraft’s Service Module engine will look firing during night flight. Coloration of the Service Propulsion System thrust chamber and skirt shows temperature ranging from 5000°F. at the chamber throat to 1200°F. at the skirt extension after a few seconds of engine operation. Glass filament is used in the thrust chamber area. The engine skirt is formed of titanium and columbium. Aerojet’s SPS develops in excess of 20,000 pounds of thrust, making it America’s largest and most powerful spacecraft rocket engine. The Service Propulsion System, produced for NASA’s Apollo spacecraft under contract to North American Rockwell Space Division, is capable of providing more than 35 separate firings of varying duration.”

Compare/contrast. Interesting that the respective glowing areas of the two engines are inverted:

Check this one out. No idea what the engine is and obviously not in flight, yet another totally different appearance:

Despite its appearance, the photograph has not been folded, spindled or mutilated. The artist appears to have used the Impasto painting technique for the overall scene, with the CSM & SPS plume painted “normally”.
I think this is the work of George Mathis.
