In Thai called "Bai Pho Tong" would be in English "Golden Leave". Made from a kind of aluminium. You buy them at the temple and people hang them on a tree at the temple for good-luck. I assume you can buy lottery tickets at the entrance of the temple. This photo was taken at the Wat Phuket in Pua. For more information about Nan province have a look at Destination Travel Guide Nan.
