I just received an unusual piece of snail mail from a Malaysian travel company called Northern Hill Tour. They used an old Spark phone directory listing for my physical address. The mail included a glossy brochure that was likely expensive to print and was mainly promotional in nature, celebrating the company's 16th year in business. Included were two scratch cards. One just said thank you when I scratched it. The other said I had won a second prize of USD $220,000! It wants me to return the card to a Malaysian address with my name, age, occupation, 'client number'(?) and address. 

The materials look very professional and well-produced. They include the company's contact details. So I tried the web site and got a 522 error. Maybe this is because so many big winners have crashed the site? 

Of course I don't believe for a moment that someone picked me out of an old phone book to send me $220,000, but I am intrigued. If this is a scam, it is a little different from the usual. Like I say, the materials are well-produced and they don't actually seem to be asking for anything. So has anyone else received anything like this, or does anyone know more about it? What is their angle here?
