A big tip of the hat to Ron Gross of Senator Street for pointing me in the direction of the Brooklyn Public Library's excellent collection of historic Brooklyn photographs.
Here, Bay Ridge Methodist Church (which I think was then called Grace Methodist Episcopal Church) stands tall over its surroundings in 1905.
The Fourth Avenue subway will not arrive until 1916. The avenue would be used mainly by horse traffic, and those wires would be for telegraph messages--doubt many had phones back then.
Here, the church in 1944.
Bay Ridge Methodist Church in 1966. Note the different clock face. This may be at the peak of its membership. If this just after two in the afternoon time was on a school day, I was probably down the avenue in Our Lady of Angels elementary school.
