An apartment with graffiti by Johnny Rotten of the Sex Pistols is an important historical and archaeological site, according to a paper published in the journal Antiquity, the BBC reported. Rotten, born John Lydon, drew on the walls of the band’s London apartment in 1975 because he disliked a recent redecoration. “The tabloid press once claimed that early Beatles recordings discovered at the BBC were the most important archaeological find since Tutankhamen’s tomb,” wrote John Schofield and Paul Graves-Brown, archaeologists at the University of York. “The Sex Pistols’ graffiti in Denmark Street surely ranks alongside this and — to our minds — usurps it.” The graffiti mainly consists of eight cartoons drawn in black marker in the upper room of the apartment, now used as offices. The authors say the drawings are “a direct and powerful representation of a radical and dramatic movement of rebellion.” The art depicts Mr. Lydon and other members of the band, including Sid Vicious and their manager, Malcolm McLaren. The current occupants of the house have said they have no plans to remove the graffiti.
