In the second half of the 19^th century, the Manifattura Ginori di Doccia had begun producing affordable blue-printed ceramics dedicated to various everyday activities, for commercial enterprises and domestic life. In the same year as the 1861 National Exhibition in Florence, the factory began manufacturing all types of porcelain, including signs for street names and house numbers, of which the first examples began to appear on city streets. 

The factory also offered plaques in more economical majolica variants, round or rectangular in shape, with rounded or squared corners, decorated with a simple double blue border and street name written in block letters. The products could be ordered in different sizes and dimensions. This type of street sign, with a clear and legible appearance, was very popular in Sesto Fiorentino, but also in Florence and many other locations throughout Tuscany and across Italy.
