The bottle was found by a diver at the bottom of a river almost 97 years to the day it was launched.
It was June 30, 1915 when Selina Pramstaller and Tillie Esper decided to scribble the note "having a good time at Tashmoo," and toss the bottle into the St. Clair River near an amusement park on Hardens Island, Michigan.
Tashmoo was a popular park that closed in 1951.
Dave Leander is the man who found the artifact, he recently took it to the Harsens Island St. Clair Flats Historical Society.
His timing was brilliant. The group is in the middle of planning Tashmoo Days to celebrate the beloved park.
In its original life the bottle held cherries or olives and was too heavy to float so it sank the moment they dropped it into the river. There it stayed until Leander pulled it out of the muck.
Members of the Metropolitan Detroit Antique Bottle Club told the Detroit Free Press they are trying to find living relatives of Pramstaller and Esper.
Giving the story even more depth, the note was written on the back of a White Star Line deposit ticket.
