In order to push out a lot of product quickly, Columbia records came up with a variety of generic and quasi-generic record cover designs in 1948-1950. This is the second 12 inch design to feature irregularly shaped squares of color with simple black drawings and lettering. There also was a different squares of color design for 10 inch lps.
This design appears to feature a stock Beethoven image. I have no idea who invented the squares designs, nor who put on things like this bust of Beethoven. Many of the better drawings were drawn by Darrill Connelly, none appear to be Steinweiss, and apparently three of them were by Andy Warhol, so other artists must also have been used.
