Birth of the Blues

I was thinking about the theme and the song title "Birth of the Blues" kept popping into my head so.....

I looked through a Sotheby's auction catalog for an image of something blue and could not believe I found "Oeuf" a painted 2 1/4 inch ceramic by Joan Miro (1893-1983).  I then looked through an old Time/Life book about The Earth and found that cool lightning strike in a desertscape.  The blue-looking lady is from a 1958 Seventeen magazine ad for skin blemishes.
