N. Colmore Fatagravure #1
I'm not yet at liberty to reveal the sources of these astounding images but I can reveal what I suspect about their origins. A Scottish adventurer, inventor, and photographer named Neville Colmore claimed to have constructed a device capable of "...parting the veil of Faery...". The device, which he called the "Spectobarathrum" along with all of the images he claimed to have made were believed destroyed in a fire. I believe some of these images and related artefacts may have survived.
