A cute baby looks out of her baby carriage with a look of consternation. Her safety in the pram is assured because she is wearing a safety belt. The carriage appears to be on a boardwalk although the photograph is likely taken in a studio in front of a back drop. The World’s Fair Photo View Company of Milwaukee, Wisconsin, took this photograph. The World’s Fair, officially titled the Milwaukee Industrial Exposition was held in Milwaukee in 1881. One of the officers of the exposition was Fredrick Pabst (1836-1904), the German-American brewer for whom the Pabst Brewing company was named. It is clear that this cabinet card photo was taken during, or shortly after 1881. This cabinet card portrait is certainly an interesting remnant of early Milwaukee, and early World’s Fair history.

I think this photo was actually taken outside when Milwaukee streets were planked with wood boards, not paved. As one can see there is a car on a street just passed the grass. Planked sidewalks were common before a city was able to cement the sidewalks.
Thanks for your comment. I never really knew that some cities used boardwalks as sidewalks. Now that i think about it, nearly every western movie has a scene showing wood plank sidewalks. Thanks again
