These are some signs I got on a recent business trip to Thailand. They were fairly inexpensive, but it was pretty pricey to ship them home.
This is a Mobil sign with Thai writing on it
This is a oil company sign with Chinese characters on it:
This one is a large cigarette sign with Thai and Chinese on it. I've got two of these and plan on selling one to finance the shipping.
I'm going back in August, so I'll be looking for more.
