What is the Surprise for Amy?

This is more like a movie than a series of still photographs.  We had a surprise for Amy when we arrived back from going to JFK.  What was the surprise, and was Amy surprised?  I will let the photographs speak for themselves!

Kathy had a brilliant idea for a surprise for Amy. I had spent a couple of hours trying to learn how to hand letter a piece of photographic background paper that afternoon.  I was doing well until the last line then I was rushing because we had to leave for the airport.  She was blown away by our sign!
