A time capsule from 1924 was unveiled at the National WWI Museum and Memorial in Kansas City, Missouri.

The 100-year-old box was laid at the cornerstone of the Liberty Memorial Tower two years before the memorial opened to the public and was found in June by officials. 

The Liberty Memorial was dedicated "in honor of those who served in World War One in defense of liberty and our country," according to Kansas City Parks and Recreation.

The Kansas City Police Department’s bomb squad inspected the capsule due to concerns about the presence of film inside the capsule.

"We were unsure if it was a type of film that degrades over time and that could have caused an explosion. Once it was determined that the time capsule was safe to open, team members worked diligently to unwrap everything and assess its condition," said a museum spokesperson via email to Fox News Digital.
