The Excelsior Shoe Factory was located on the present corner of Benjamin Franklin and Carlos B. Zetina Streets (named after the man who founded Excelsior in 1902 who later became a senator, as well as presidential candidate) in the Tacubaya district of Mexico City.
Salviati made a mosaic in the crescent over the entryway representing Labor.
Today, the Universidad La Salle stands in the location.
