It may not seem to Lovecraftian, but this hotel next door to me is full of stuff like this wall. I could easily see Hemingway sitting here and writing a novel. In fact, last night I started the very preliminary work for my next novel. This one is going to be a horror one. I'm getting myself ready by reading "At the Mountains of Madness."
BTW, this mountain is very real. It is the Uluguru mountains and I walk by them every day. There are no zebras (at least there aren't any more) there is actually a soccer pitch where the painting shows zebras. The horror!
