I can't find out much about Laurence W. Chaves the artist, but I want to. Someone on the Lamentations of the Flame Princess facebook group posted these illustrations from Thomas De Quincey's Confessions of an English Opium Eater. This comes at a time when I'm researching an underwater hex-based adventure, so it's quite inspirational. These remind me of the work of Gustav Dore or Alphonse de Neuville. Great stuff.
