In 1937 King Carol II of Romania paid a state visit to Poland. The parade pictured is in the Polish city of Krakow. The King is seen in the lead automobile, a 1929 Buick Phaeton, 7 passenger. With King Carol II is the Polish President, Ignacy Mościcki, they were there to inspect Polish troops.
As in many European countries, particularly in the East, Buick was held in such high esteem to the point where Cadillac’s were often seen in parades as the following vehicles with the biggest Buick carrying the dignitary of the day. In this photo the second and third cars could be Cadillacs and there are unidentified later model cars in the distance.
