Thailand Post has joined hands with Khao Kheow Open Zoo to spread the joy of this pygmy hippo in the form of iStamps, or personal stamps, which feature photos of a day in the life of little piggyback and postcards of adorable poses, so that everyone can collect and share this heartwarming happiness with others. There is also a special iStamp collection where you can turn your own photos into stamps. Stamps are a medium that opens up the world of learning and is the voice of the country.
