Launched in 1935, the San Mao comics are one of the longest running comic series ever. They cover the chaos of society following the invasion of Japan, and then celebrate the liberation of China by the Communists from 1949. They were extremely popular and still very famous in China.
The title of this comic roughly translates to "Reduced Price Bidding". Here, San Mao attempts to sell himself alongside a peasant trying to sell his children to make ends meet.
