The Boston Public Library has posted a number of photos by Herald-Traveler photographer Leslie Jones of the city's 300th-anniversary celebrations in 1930, including several showing the temporary arch the city erected on the site of what's now City Hall. Worth looking at large for all the details. And here's the reverse view, showing what was then an expanded Dock Square (now City Hall and City Hall Plaza). No doubt, Sam Adams just stood there, glowering.
