Throughout May 2014 P M Buchan was part of the CULT exhibition at Orbital Comics, London, as part of the GHOSTS comics art collective. Alongside Andrew Tunney, Mark Penman, Jon Lock, James Lawrence, Owen Michael Johnson, and Nich Angell, Buchan and John Pearson collaborated on a triptych of images inspired by the early lives of members of the Manson Family. The exhibition included a group signing and launch event with live art, live music and performance by Johnson's Kittelbach Pirates. Liz de Jager, author of The Blackhart Legacy trilogy, said: "The CULT exhibit fulfilled the hype and promise of its enthusiastic team of creators. The art was darkly evocative and thoughtful, leaving a sense of disquiet behind. Overall, a very strong showing for a brilliant bunch of up and comers."
