The graffiti in Gerbergässlein is probably the best-known piece of street art in the centre of Basel. Every day, people stand in front of it and admire the huge mural, take photos or guess at the subjects. The work was commissioned by the rock bar L'Unique across the alley. Appropriately, the wall features world-famous musicians. If anyone can't find his or her favourite musician, they should make a suggestion to the landlord. The work of art is thus constantly evolving and immortalizing the world's most famous superstars.
