Staircase Model (France), mid–late 19th century

This double-revolution staircase model is similar to one described as being "in Renaissance style for a store," in plate 17 of a folio by E. Delbrel, published in Paris in the 1880s. The upper level is self-supporting and the railings' balusters are turned.
