Exquisite pinless buckle* or applique showing a design of a flower in an undulating vine. It's a stamped piece, so the metal starts out about 0.7mm thick sheet and then is raised up to 3.7mm thick in relief (just over 1/8"). 62mm (about 2 1/2") tall by 47mm (1 7/8") wide.
Made in a sixth-generation metal stamping factory in Paris, France, by using stamps created more than a century ago. The machinery used is similarly old and sensitive, requiring a fine, trained hand.
*If using as a buckle, it's best used with stiff or thick fabric, since the 'center bar' curves and undulates.
