Fifty acorns tied in a sack

To celebrate the 40th anniversary of John and Yoko's Acorn Event where they sent acorns to world leaders asking them to plant them for peace, Yoko is planning to recreate the event tomorrow (Saturday May 2nd 2009). She will send 123 leaders a box marked "Acorn Peace by John And Yoko, Spring 2009" and containing two acorns.
