But that’s not all! ‘AgentQ7’ pointed us to the Hershey’s Iron Man site where, if you click on ‘Enter Reese’s EXPO Pavilion’ and then on the door with the S.H.I.E.L.D. logo on the left side of that page, it brings you to a window to enter a password. Enter ‘17033’ (the answer to the hint given in the bottom right of that window) and then click on the picture grid/screen on the right and it takes you to many photos that were not included in the press kit send out by the studio!
