‘Colectivos’ are the thundering city buses that transport Porteños (inhabitants of Buenos Aires) around the city for the equivalent of 17p. The designs are generally old-school, hand-painted and fantastically varied, helping you spot the bus you need before you can read the number. The interiors are often highly decorative and also transport you to previous decades.
I took these pictures in Plaza Italia in Buenos Aires. I got some funny looks from members of the public. Perhaps they'd never seen a bus-spotter dinosaur before.
