Many of the old spice houses have however changed their trade to the export of antiques. Room after room of teak boxes, Rajasthani doors, Chettiar enamel tiffin carriers and Chinese pots wait in the half light ready to be shipped anywhere in the world. In amongst these large warehouses, that are part museum to those that can't afford it and part shop to those that can, are the smaller tourist traders. "Hello, hello, hello", they call, "looking is free". Mirrored belts glint in the sun, alongside lacquer boxes, oldish bronze statues and black and white photographs of grandfathers, grandmothers, mothers and sons. Strangely, little is from Kerala or Kochi for that matter, whether it is new crafts or old. Browsing these stores, I meet the new invader, the tourists.
