The author talks about Waterhouse rushing through the streets of London to get to his studio. I wanted to show what he was thinking about, which is why we see the dinosaur ghosts hovering around him, and I've tucked under his arm a portfolio of dinosaur drawings, which is coming loose, and the pictures are blowing down the street into people's hands. Since many people at the time had never heard of dinosaurs, I thought this would be a good (but subtle) way to show how Waterhouse was in many ways responsible for the public's education in dinosaurs.
