Hawk's Personal Traveler  LbNA # 12557

Clues

Of these, I have many --
In brown and white and red;
But if you get caught with any
You'll be fined an amount you'll surely dread;
But if you ask me for one of mine,
Some time when we meet and talk,
You won't receive a horrible fine --
For I am a letterboxer, and I am the Hawk!
