A 48-star mystery
The Courthouse in Grant County, Minnesota was built in 1905. On June 24, 2005, in a celebration of the 100th anniversary of the Courthouse, the time capsule placed in the corner stone was removed and opened.
What the people who opened the time capsule found has presented a mystery: a 48-star flag. In 1905 there were only 45 states in the United States, meaning that the U.S. flag would only have had 45 stars on it.
