How do I write an invitation for a party hosted by a mayor and his wife?

The only thing that changes on an invitation hosted by a mayor and his wife is how you list the hosts' names. You should write "The Honorable Mr. [Mayor's name] and Mrs. [Mayor's Name]" and then invite your guests to the event. So, for example, if the mayor's name is Tim Jones, you would write "The Honorable Mr. Tim Jones and Mrs. Tim Jones request the pleasure of your company..." Alternatively, you can use the mayor's wife's full name: "The Honorable Mr. Tim Jones and Mrs. Jessica Jones request the pleasure of your company..." The rest of the invitation should follow the form appropriate to the even that the mayor and his wife are hosting.
