I was recently in 1520 Market Street, informally known as “City Hall West,” and before that the former Federal Building, when my curiosity was piqued by the sculpture in the middle of the lobby. It turns out it has a whole story, dating back to the construction of the building in the early 1960s. It is entitled, “St. Louis and the Mississippi,” sculptured by local artist Robert Cronbach. The top represents the source of the river, and the huge “tongue” connotes St. Louis, and the remaining sections are the course of the Mississippi as it flows to the Gulf of Mexico. I guess.
