What was in those envelopes at Bush Sr.’s funeral?

I don't know if you've seen the video or not, but it's very strange that all of the president's wives were given these envelopes during the funeral and when they opened them, nearly all of them had a shocked and worried expression on their faces. Especially Laura and Jeb Bush. You can see the shock and horror in Jeb Bush's face as Laura tells him whats in the envelope.
