Warp Artefacts - This used to be the imprint of BL Publishing that marketed official artefacts from the worlds of Warhammer and Warhammer 40,000; including art prints, clothing and life sized replicas of Warhammer items. Early 2006 they were brought closer to Black Library under the banner of BL Merchandise.
