Cartão Flag of Amsterdam

This design features the flag of the Dutch capital city of Amsterdam. The flag depicts three Saint Andrew's Crosses and is based on the escutcheon in the coat of arms of Amsterdam. Design journalist Roman Mars declared it, in 2015, to be the most "badass" city flag in the world. AFC Ajax, an Amsterdam-based football team that plays in the Dutch Eredivisie, uses the Amsterdam flag as their captain's armband. Amsterdam is colloquially referred to as the "Venice of the North", because of the large number of its canals which form a UNESCO World Heritage Site.
