Published in issue 36 of Weirdbook, edited by Douglas Draa, “The Black-and-White Dozen” concerns a man looking through a stack of a dozen pornographic photographs previously belonging to his father, unaware each time he does so, he opens a portal to the past where these horrifying images were captured.
The negatives were buried deep underground in an archive of such atrocity, their eventual discovery will haunt the nightmares of whatever institution is tasked with cataloguing them. Some things—no matter how many generations old they are—will never be fit for museum display. (Excerpt from “The Black and White Dozen”).
The story receives an honourable mention in Ellen Datlow’s The Best Horror of the Year Vol 10.
