Made In France Stamped Demitasse Espresso Cup and Saucer

Lovely little French demitasse espresso cup and saucer. Black cup with floral motif and solid black saucer. Cup is stamped “FRANCE” “N6” and “45”. Saucer is stamped “FRANCE” and “6”. I am not familiar with the marks, so I do not know the manufacturer, unfortunately. There is one tiny scratch on the saucer, but no other flaws. Please look at all pictures. It appears to have only been displayed. So cute!! Not a thrift store purchase. App. Cup measurements: 2-1/4” x 3-1/8” Saucer is app. 4-1/4” square
