Province of Las Palmas
The tricolour flag has its origins in the "Canarias Libre" movement of the 1960s. It was designed by Carmen Sarmiento and her sons Arturo and Jesus Cantero Sarmiento, and first displayed (in paper form) on 8 September 1961. It combined the blue and white colours of the Province of Santa Cruz de Tenerife (Province of Canary Islands) with the blue and yellow colours of the Province of Las Palmas.
