A sample invitation letter for a Teacher to attend a school celebration in their honor. The invite is direct and forthcoming without giving away any surprises to the teacher.

You are cordially invited to the Teacher's Day Gala event on September 9, 2010 at the Albert Hall at 7pm. I hope you could grace us with your presence. Special guests, students and attendees are looking forward to seeing you at this wonderful event.
