"It's a lie that you must have a logo in the ad. If you write a letter to someone and the most interesting thing in the letter is your signature, you've wasted your time. You ought to be able to write a letter, not sign it, and everybody ought to know who it comes from because it's written in your tone of voice, your handwriting, and about the things in which you're interested. Most people could write a letter without signing it and the recipient would know who it came from. If nobody knows you, then you need to sign it." - Neil French
