Skateboard Ikurriña with Lauburu symbol

The ikurrina flag (in Basque) or ikurriña (Spanish spelling of the Basque term) is a Basque symbol and the official flag of the Basque Country Autonomous Community of Spain. This flag consists of a white cross over a green saltire on a red field. The lauburu (Basque: lau ("four") + buru ("head")) is an ancient hooked cross with four comma-shaped heads and the most widely known traditional symbol of the Basque Country and the Basque people. In the past, it has also been associated with the Galicians and Asturians. Flag image attribution: Daniele Schirmo aka Frankie688, CC BY-SA 2.5, https://commons.wikimedia.org/w/index.php?curid=437465
