From left to right, these are the oldest known coats of arms of Croatia, the Republic of Dubrovnik, Dalmatia, Istria and Slavonia, adorned with bands of gold, red and white stripes extending down vertically. Atop the shield there is a Croatian tricolour ribbon with golden letters RH that stand for the Republic of Croatia, executed in Roman square capitals. The presidential standard is flown on buildings of the Office of the President of Croatia, the residence of the president, transportation vehicles when in use by the president, and in other ceremonial occasions.[56] The presidential standard was designed by Miroslav Šutej in 1990.[57]
