I like the covers of the books referred to in the previous two posts: the book about Kay Kyser, brought out recently by BearManor Media, and the cover of Ricky Riccardi's new book about Louis Armstrong. I also like the cover, to the left, very much: it's the cover of Martin Grams, Jr.'s latest book (his radio-related and television-related books have been referred to in previous posts). The book (which I recently got, but have not yet read) is The Shadow: The History and Mystery of the Radio Program, 1930-1954.
Here is the amazon.com link for the book:
