Map of Spain. Distribution and nomenclature of the Spanish regions according to the draft of Law on Local Government and Administration, released on 20 July 1891 by Minister Francisco de Silvela. The provinces of Oviedo and Gijón, and the two resulting from the division of Salamanca were included in the Draft of Law, but are drawn arbitrarily by the author of the map, since no information is known about the municipalities that were included in these new provinces.
