Here is the first page of a sales letter that can be used with this item. 

Dear Friend:

As you can see, I have attached a nice, new, crisp, Belarus 50 Rublei Bank Note to the top of this letter.  Why have I done this?  Actually, there are two reasons:

1.  I have something very important to tell you, and I needed     some way to make sure this letter would catch your attention.

2.  And secondly, since what I have to tell you can save you a great deal of time and money, I thought using money, even though it's not real, as an "eye-catcher" was especially appropriate.
