Yves Saint Laurent Pins & brooches Golden

Large YSL brooch in gold metal (gold plate),
on the back "made in France", as well as an E number4.
Hauteur: 5.5cm
Largeur: 3.5cm
Very good condition, Perfect gilding, no scratch, note however a manufacturing defect on the bottom of the L (photo 2)
This pin should not be compared to the more easily found one (the back is smooth and has no number, neither made in France,( see last photo)
