Here are four designs by Darrill Connelly. One of them also shows a reissue with a different catalog number, OL instead of ML Most of his work at Columbia was illustrations that he did for covers designed by others, mainly Steinweiss. These four may be entirely his own work. There are not many covers like that. If the Masters of the Keyboard are not his designs, just his illustrations, at least they allowed him a larger canvas. I love these Masters ones, and wish I had the other 2 or 3.
