Help Identifying and valuing antique frame by A. Dyrenne, Paris 1882

[Thetiller3]

Hello everyone,

I recently acquired an ornate antique frame and I’m hoping for some help with authentication and valuation.
   •   The back is engraved: “A. Dyrenne, Paris 1882.”
   •   Material: appears to be cast bronze (possibly brass or iron) with a dark patina.
   •   Style: highly decorative Rococo/Baroque revival with multiple cherubs/putti, scrollwork, and floral details.
   •   Size: 15"x9"
   •   Weighs approximately 6lbs
From what I’ve read, Auguste Dyrenne was a Parisian bronze/cast metal maker active in the late 19th century. I would love to know:
   1.   Does this engraving seem authentic for Dyrenne’s work?
   2.   Would this have originally been a picture frame, mirror frame, or something else?
   3.   What is the approximate resale/collector value in today’s market?

I’ve attached photos of the frame (front and back with the inscription). Any information, references, or advice would be greatly appreciated!

Thank you in advance for sharing your expertise!

The famous foundry that made the cast iron pieces spelled was/is spelled  A. Durenne.

Without handling this it would be hard to tell if it was an original piece (weight, quality, crispness of design).  However, the precise inscription is suspect.  Copies of this same frame have been produced and are still desired. Many replicas are generally stamped with a product code on a leg.
