The northern Brazilian city of Boa Vista must have the cleanest car windscreens in the entire country. This is because on almost every street corner, at every junction, and around every roundabout, there is a Venezuelan, or four, offering their services. Their partners and children sheltering from the sun in some nearby shade.
Whether they were teachers, builders, doctors, carpenters, chefs, farmers, bankers, or shop assistants previously, they are now self-employed car washers and roadside salespeople. Cardboard signs serve the dual purpose of promoting their work and potential, whilst also providing some cover from the intense heat which accompanies their daily 12-hour shifts.
