It’s hard to miss Robert Montgomery’s work. The Scottish-born artist, who took a strong interest in situationism and Marxism at university, spreads his simple and provoking poetry across the world through installations and (often illegally placed) posters.

Whether it’s in the form of a 12ft-tall billboard, a dazzling neon sign, words set ablaze in the gardens of the Louvre, or on the garments of one of our favourite brands Each x Other who he regularly collaborates with, the artist’s haunting poetry stays in the mind long after the physical artwork is gone.

His first monograph, a self-titled ruby red tome, has just been published and you can read an interview with Robert on Dazed.com.
