This person discovered the bottle earlier in 2015:

Marianne Winkler found the bottle in April on a beach on Amrum, an island off Germany’s North Sea coast. Winkler told local website Amrun News, “It’s always a joy finding a message-in-a-bottle on the beach. Where does it come from, who wrote it and how long has it been travelling with the wind, waves and currents?”

What would you do if you found this kind of message?  Would you donate it to a museum, keep it as an artifact or sell it on ebay? 😉
