Question about correct way to address a letter

Like many of y'all, I'm considering entering the Backspace Query Contest but I'm sort of confused on the correct way to address the letter.

It's a query, so normally it would be addressed to a specific agent, but this one is going to "Sara Kendall's Holding Pen, Nancy Coffey Literary & Media Representation." It will be read by one of four well-known agents.

So how do I address it correctly?

Thanks,

Lucie

I thought it was just me, but I'm thinking after 18 views and not one response--

Well, maybe this is just something I'll ned to get creative with.

Any thoughts welcome,

Lucie

Thanks y'all. I went with "Dear Backspace Judges:" I know it's not terribly flashy, but I didn't want to say Dear Agent and didn't want to attract too much attention to the opening.

Thanks anyway,

Lucie
