Who is Dorothy Snell?

Who is this Dorothy Snell and why is her name on my helmet?

 Come to think of it, her name is on my wife's helmet, too.

 Maybe she designs helmets? I like my helmet . . . I wonder if Dot designs other gear besides helmets? Are there gloves?

Okay. Yes. I know Dot Snell is not a person. I know what the sticker means. But why not have fun with it?

We could promote motorcycle safety with the creation of a cartoon character.

Dot Snell says, 'Always wear your helmet!'

Kind of like Smokey Bear for the two-wheeled set.
