Requesting Photos Signed by Entire Show Casts

[Chris102]

Would someone be kind enough to tell the correct protocol for requesting a photo signed by the cast of a particular show? Do you address the envelope and letter to the name of the show?

Well if you were sending to the cast of let's say OTH then you would address it

One Tree Hill Cast
address

you would write

Dear One Tree Hill cast
_______________
________
______

Can you please autograph a picture of you guys.

Your fan

I wasn't sure on how to address the envelope/letter. Your help is greatly appreciated!
