The Mermaid on the back of the "Hello Sailor" tee comes from our backpocket flasher you can find on all Amsterdenim jeans. Designed by Amsterdam artist and signpainter Martijn Krabman. A reference to Amsterdam's rich nautical history. In the Dutch Golden Age (17 hundreds) Amsterdam was the most important port in the World. This is why Amsterdam is also called "Venice of the North". The color blue is a reference to one of the things Amsterdam is known for today, being the 'Denim capital of the World'.
