A French Dentist's Token From Normandy

One of my many interests is tokens connected with surgery and dentistry. Dentists' tokens are uncommon, especially here in the UK, but they do turn up from time to time.

This example is from the town of Falaise in Northern France, issued by a Monsieur Breard Junior. I have not been able to find out anything about the issuer, although he was obviously a dentist in the town.

I would be interested to know an approximate date of issue, and whether this is purely an advertising piece or whether it might have had limited circulation in the local area.
