Photographer Gustavo Sanabria has a lovely photo series that provides a peek into Bangkok, Thailand’s industrial Talat Noi neighborhood.
Via Google Translate:
Talat Noi is the name of a neighborhood south of Chinatown in Bangkok along the Chao Phraya River. Formerly was home to most of the blacksmiths, tool steel producers. After the Second World War blacksmiths had to adapt and become mechanical. Now a network of alleys full of shops and parts stores.
