It’s the promo poster for “In the Heart of the Sea”, the film about the whaleship Essex. (The basis for “Moby Dick”.)
I was awestruck first time I saw it. It captures not merely the tenor of its movie, but – for me – the essence of good spec-fiction writing; there is a sense underneath of larger things, moving. The story is merely the bits that break the surface, the indicators of some terrible, wonderful immensity.
To continue the analogy; every story is another throw of the harpoon and the desperate prayer my aim is true.
