Here are the specific details regarding its age and markings:
• Production Era: This particular "winged crown" style backstamp featuring the text "Plant Tuscan China" was famously introduced in 1936 and used through the mid-20th century. Given the overall Art Deco flair of the green panels and filigree texturing shown on the set, it most likely dates from the late 1930s to the 1940s.
