When I worked for Six Flags Corporate Office in Los Angeles I designed the largest birthday card in the world with over 4 million signature that were attached with 7 rolls of paper, each roll had signatures of visitors to our seven amusement parks across America. Vice President Nelson Rockefeller formally accepted the card on the front lawn of the White House. I took this photo of Joseph Heitzler, PR Director and Ned DeWitt, President of Six Flags, with their spouses after the ceremony.
