The City Seal of Los Angeles 

A.  Yes, as indicated in the article "Rosary Retained in L.A. City Seal" quoted below.

"The Rosary, if there were any doubt about it, is officially and definitely a part of the seal of the City of Los Angeles.  Minor variations in the city seal, including occasional omissions of the beaded circlet were ordered ended in a City Council ordinance signed January 6 by Mayor Sam Yorty. The Rosary -- ten decades at first, and the seven-decade Franciscan Crown since 1949 -- has been part of the city seal since it was adopted in March, 1905. But in recent years, some city councilmen and departments used a simplified seal  in their letterheads; the beads sometimes become a solid line. Mayor Yorty wrote the city council in 1966 urging adoption of a uniform seal. The Cultural Heritage Board approved an official seal last year and sent its recommendations to the City Attorney. These were adopted in the council ordinance signed by the mayor. The Rosary or Franciscan Crown represents the Franciscan fathers who civilized and settled in much of California, according to the Mayor's office. The city shield, surrounded by the beads, includes the stars and stripes of the Unites States, the California Bear Flag, the eagle and serpent from the arms of Mexico, and the castle of Castile and lion of Leon from the arms of Spain.  Sprays of olive, grape and orange suggest the location of Los Angeles as a 'city set in a garden'."
