Etching on paper realized, among the others, by Tomàs Gozàlez. from Juan Corradi, Descubrimiento y conquista de la América o Compendio de la historia general del Nuevo Mundo, Madrid, Imprenta Real, 1803 (translated by William Robertson, History of America, Edinburgh,1777). At the bottom margin are the indications of responsibility: Tomás González (principal author), José María Cardano, Felipe Cardano (engravers), Juan Morata y Gangoiti (engraver of the text). Rare map of Mexico, Texas, Alta and Baja California, Rocky Mountains and contiguous regions, published in Spain at the beginning of the 19th century. Fascinating topographical restitution, finely engraved and with good representation of the hydrography of the rivers of the region, although it retains an unnamed lake, Timpanagos and a Rio de Dolores that flow into the San Francisco Bay. The lack of detail in the map is probably a product of the Spanish doctrine of secrecy in the regions then controlled by Spain: it allowed a topographical representation of the region but omitted place names. Three margins as originally, left resected at the framing line. Editorial folds from insertion in volume. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
