doubt - google searched it.
As for the letter. I used google image search and typed in Letter
Here is a so so example. You need to put a 41 cent stamp on the top right hand side of the envelope and be sure it weighs less than an ounce I think.
Then for instuctions I used google and typed in How to mail a letter and got this:

Hopefully it helps. Google is wonderful.
Edit: Yeah, price to send mail is now 41 cents and depending on your area you might not want to put your red flag up. Where I live you don't put it up ever and the mail people check all the boxes because of mail theft. Your area may be different. Just look down the street and see if people do or not.
