French Demitasse Cup and Saucer

Lovely little demitasse cup and saucer. Black cup with floral motif and solid black saucer. Cup is marked “FRANCE” “N6” and “45”. Saucer is marked “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!! App. Cup measurements: 2-1/4” x 3-1/8” Saucer is app. 4-1/4” square
