Alex Steinweiss designed covers for Columbia from 1939 to the mid-1950s, about 16 years. He designed for Decca including Coral/Brunswick from the early to mid-1950s until at least 1969, an equally long or perhaps longer period. Here are some of my favorite Steinweiss covers from Decca. I am grouping them thematically. The first few are the photographic style that he used so much at Everest and for London. None of these are signed, so I could be wrong about Steinweiss being the designer.
