German mothers would pass on their childhood kitchens to their daughters, which became a widespread practice by the nineteenth century. By this custom, Nuremberg kitchens that might have been very up-to-date when first made would be noticeably old-fashioned after decades of being handed down as a family heirloom. Similarly, while many nineteenth-century German toy manufacturers offered miniature versions of all the latest kitchen gadgets, their catalogs also showed toy kitchens that went virtually unchanged for decades, as did many of their pots, pans, and dishes. Thus, late nineteenth- and early twentieth-century examples often incorporate components that were distinctly anachronistic by that time.
