Overview
- A mother and daughter visiting the National Gallery noticed a white mark on the shoe of Ferdinand Bol's Portrait of a Boy and shared a photo that circulated widely online on Friday.
- The image has been widely described by tabloid and viral outlets as resembling Nike's swoosh and has prompted joking claims about time travel.
- The National Gallery acknowledged visitor interest and posted a tweet inviting viewers to spot modern details, saying the picture had been popular with visitors.
- No art‑historical, forensic, or trademark analysis has been reported that confirms the mark is a modern logo and the rest of the sitter's clothing matches 17th‑century dress.
- Experts and commentators point to pareidolia or coincidental paint or restoration marks as more likely explanations, and the episode highlights how social media can turn minor visual details into viral claims.
