Greetings Audrey – What a wonderful beveled glass mirror, this looks to be a bronze, wood and metal base. I’ve not found a record of this specific model coming to market before. In these cases, I compare your piece to stylistically similar examples to determine are reasonable value.
In this case similar French mirrors without the Hermes cachet are priced at $1250USD in online retail galleries as an authenticated Hermes piece, I think closer to $3250USD and at auction $1250USD. Thank you for thinking time to share this piece and do let me know if you have any follow-up questions.
Sincerely,
Erin-Marie
