The Merchant Flag of Spain (including Imperial), was a set of colors designed to identify Spanish Cargo and Trade Ships on The High Seas. Most Countries used some form of Merchant Flag. Most bore “Imperial Colors” (or hues), rather than actual imagery or symbols. Since 1785, Spanish Merchant Ships generally flew a Flag which ranged around 15x15 feet. It was typically flown from the Rear of a Vessel (Stern). Coloring was indicative of The Spanish Monarchy, and featured a Golden Yellow Field for the entirety of The Flag. (2) Red horizontal Stripes were placed, with one closer to the top of the Flags and the other on the lower. The Spanish Merchant Flag was used continuously unchanged until 1927, when The Nationalist Flag was used for all forms of transportation identification in Spain.
