President Dwight D. Eisenhower is riding down SW Broadway in this undated LIFE magazine photo. I believe this is 1956, as he made a west coast swing in October of that year during the presidential campaign. He’s riding in the “bubbletop” 1950 Lincoln Cosmopolitan limousine which I don’t think would have been available to Ike in 1952.
The cross street immediately behind him is Washington Street. The Plaza Hotel is now Hotel Vintage Plaza and the Bank of California building replaced the Union Pacific and Liberty Theater block on the left.
