Hide-A-Key

I have a little hide-a-key box that I use in case I get locked out. It's quite convenient, but there's one thing about it that makes no sense to me:


Why does the "Hide-A-Key" box have a picture of a key on it? If you're the one who hid it, aren't you going to remember that there is a key contained inside? Do most people have dozens of little metal boxes scattered around their yard so that they need to label the one that contains the key? Furthermore, isn't the picture just going to make it easier from someone other than yourself to identify the contents of the box?

Am I the only one who has thought of this?
