As I mentioned in the first link, "It seems that Gotschke was self-taught, but had little trouble understanding how to portray machines and settings accurately with strong doses of atmosphere and emotion. When necessary, he could change his style to tight rendering. Sadly, he started losing eyesight around 1985 and was blind by 1990, some ten years before his death."
Although I've viewed his work in publications for many years, I don't recall ever seeing one of his illustrations in person. Until recently. In February I visited the Mullin Automotive Museum in Oxnard, California. It has a fabulous collection of French cars mostly from the 1920s and 1930s. There also was a small section devoted to automotive art that included one of Gotschke's "impressionist" style illustrations that I photographed and present below in a detail.
