This picture illustrates the ill-fated expedition to Australia described in H.P. Lovecraft’s horror story The Shadow Out of Time. The images in the montage are edited versions of public-domain pictures, and include this copy of the Necronomicon. The complete image is © Anthony Dekker.
“… On July 10, 1934, there was forwarded to me by the Psychological Society the letter which opened the culminating and most horrible phase of the whole mad ordeal. It was postmarked Pilbarra, Western Australia, and bore the signature of one whom I found, upon inquiry, to be a mining engineer of considerable prominence. Enclosed were some very curious snapshots. I will reproduce the text in its entirety, and no reader can fail to understand how tremendous an effect it and the photographs had upon me. …”
The “Pilbarra” in this story (and on the map) is presumably Pilbara Road District, an old name for what is now the town of Port Hedland, Western Australia (although the address given by Lovecraft matches a no longer extant street in the nearby ghost town of Cossack). Lovecraft’s story also refers to a precise geographical location: 22° 3′ 14” S, 125° 0′ 39” E. See more on the Australian aspects of the story at Trollunteer. Propnomicon also did some really good props a few years back.
