Set of 3 hand painted China Jingdezhen plates

These plates likely date to the 1970s or 1980s.
• The Mark: Stamped iron-red marks like this became the standard for export wares following the Cultural Revolution (post-1976).
• The Style: The design is a "Famille Rose" style, specifically the "Butterfly and Gourd Vine" (or Melon) pattern. This was a very popular motif for export to Western markets during this era because it combined traditional Chinese symbolism with a colorful, decorative aesthetic.
Artistic Significance
• Pattern: The butterflies represent long life and joy, while the gourds/melons and vines symbolize fertility and "endless generations."
• Technique: These are typically transfer-printed designs that have been finished or "heightened" with hand-painted enamel colors to give them texture and vibrance.

One plate has a chip in two of the painted leaves, please see the 5th photo and review all photos well.b
