What was the "Join, or Die" poster about, and who created it?

It has been awhile since I talked about this but I will give a try and hopefully I help. The it was a cartoon it was made by Benjamin Franklin i don’t know if he did do the poster too but it was made in early 1750’s so it was around the time of Franklin published by an American colonist. It had the names of the American colonies on it. ( it was for colony union) I know more about the cartoon but I bet it was still made by Benjamin. I REALLY HOPE THIS HELPS.
