some information from the sender:
I'm currently visiting Nong Khai, a Thi-Lao (Thailand and Laos) border town in northeastern Thailand.
This cards shows the typical harvesting of rice. Scenes like this still exist not only in Nong Khai (where this card is from) but all over southeast Asia and Taiwan. We have straw hats too like the one worn by the farmer on this postcard.
