CHICAGO — A time capsule from 1968 put in the building formerly known as the John Hancock was opened exclusively for WGN News on Monday.

There were 20 items inside the time capsule. Some of the items made complete sense, but there were some that presented more questions than answers as to what was going on in Chicago 50 years ago.

Employees at the now 875 North Michigan Avenue building cracked open the capsule and revealed the following items:

1. Microfilm (they have no idea what’s on it)
2. Letter from Mayor Richard J. Daley
3. Wooden section of John Hancock’s staircase from his home
4. 1968 Chicago Cubs signed baseball (by whole team)
5. Piece of Eiffel Tower
6. Postage stamps from 1968 (value 6 cents)
7. Business Cards – stack of them signed by employees of John Hancock Insurance Co
8. Golden Bull-from Chicago Bulls
9. Roll of film (no idea what is on it)
10. Letter written by John Hancock (dated 1792)
11. Medallion commemorating 150 anniv of state of IL
12. Crystal elephant given by Sen. Everett Dirksen (R)
13. Unmarked Hockey Puck given by Chicago Blackhawks
14. Book written by then IL Gov. Otto Kerner: Report of the National Advisory Commission on Civil Disorders
