Street Art Weekly: SF's Double Barrel Graffiti, El Salvador's Mural Festival, and Glasgow's Pillars Erased by Batman

other · 2026-08-26

This week's BSA street art update highlights three unique stories. In San Francisco, a striking vertical double barrel Taiwanese graffiti piece on a skyscraper has elicited mixed feelings from locals; while some admire its artistic lettering, others are weary of unauthorized tags. Dogwalker Natalie Price remarked in the San Francisco Standard about the creativity involved in the lettering. Meanwhile, in El Salvador, the PigmenTrip Muralism Festival, initiated by Isaac Sosa, has been revitalizing walls for eight years amid ongoing debates over President Nayib Bukele's gang crackdown since 2022. Sosa shared with Barron's that art serves as a 'magical tool' for 'social transformation,' with residents noting increased safety due to the murals. In Glasgow, the 'Art Under the Bridge' exhibit, showcasing 23 painted pillars by various artists beneath Kingsbridge, was unexpectedly covered to advertise a new Batman film, with the Scottish media neglecting to acknowledge the artists, including Phill Blake and Mr Cenz. The weekly interview features works by Cern, Dan Bunn, and others, accompanied by photos from Jaime Rojo.
