Going travelling soon?
If so, you might want to read this book review on H-Travel. The book is about the encounters between souvenir sellers in Sumatra and Western tourists, and sounds like many a scene that I've seen.
In fact as I write, eight masks, from eight countries look down from the wall at me. Those are Indonesia, Cambodia, Sri Lanka, China, Tibet (although bought in India), Egypt, Thailand and southern India. I know they're tourist "tat", but they're still evocative!
