English: War flag for Spain proposed by Antonio de Caula y Concejo, a painter, curator of the Naval Museum and genilhombre of Alfonso XII, in 1908. The design was proposed as an effort to address the concerns of a minority in the Council of Ministers who opposed the indistinct use of the national banner for both civil and military contexts.
