Yes, that is Andy Warhol on the Andy Sock Hole socks.
Pop art socks you could say, as these feature the most famous pop artist of all time. It’s just annoying that so few people will see them when you stick your shoes on.
They are available in two adult sizes, selling got £7.50 a pair. If you like the idea, but not Warhol, other characters are also available at the retailer’s site.
