The market is an extraordinary mixture of cultures, age groups and objects - most of which are unwanted. Half-empty bottles of whisky line up beside broken toys. Old VHS porn films sit next to defunct mobile phones from the 90s. Yet people come from far and wide to pore over these ragtag piles in the hope of unearthing a gem, eventually going home with a 20-pack of white sports socks and a statue of Jesus with its nose missing.
