Josef Müller-Brockmann designed amazing "concert" posters. Some are published in a nice Lars Müller Publishers book "Josef Müller-Brockmann - Ein Pionier der Schweizer Grafik" (ISBN3-907078-59-4). You can see two posters from that book right here. The image on top is a desigen from 1953, the second poster is from 1958. Reid Miles who is a great talent, did his Blue Note Records cover art maybe in late 1962 (Freddie Hubbard, Hub-Tones, Blue Note Records BST-84115).
