This is a collage I created using random images from old scanned newspapers (you can find them at news.google.com/newspapers). It's a poster for a non-existent event. The background gradient is based on those used for band posters in the '60s at places like the Fillmore. Click to enlarge (1561x2118 pixels - opens in a separate window). Credits below.
