Illman said she found the bottle near her son’s car.
"My friend Grace Ricciardo and I were walking across the dunes when I saw something sticking out of the sand so I went to take a closer look," Illman told the museum. “It just looked like a lovely old bottle so I picked it up thinking it might look good in my bookcase. My son's girlfriend was the one who discovered the note when she went to tip the sand out.”
Illman said the note was “damp, rolled tightly and wrapped with string.”
Experts said the bottle was a 19th century Dutch gin bottle, CNN reported.
“Incredibly, an archival search in Germany found Paula's original Meteorological Journal and there was an entry for 12 June 1886 made by the captain, recording a drift bottle having been thrown overboard,”Ross Anderson, the museum's assistant curator Maritime Archeology, told CNN. “The date and the coordinates correspond exactly with those on the bottle message.”
The museum did not reveal what the exact message was.
