This is a very nice Whiting & Davis purse, and in nice condition.
These bags are not my area of expertise, but I believe this is what is referred to as a "Poirier Pouch", which would date it to the 1930's.
Does have the correct silk lining, and silk Whiting & Davis tag on the interior.
Genuine Whiting & Davis bags are usually stamped with both a serial number, as well as the W & D signature on the inside of the frame. This one has only the number (see photos), however, everything else about this piece retailer would suggest that it is genuine Whiting & Davis.
There are a couple of small issues: There is slight staining on one of the inside corners of the lining (may come out with cleaning). Also, there is one tiny piece of gold mesh missing on the bottom of the bag (again, see photos).
The frame is in very nice condition, with no rust.
Very small amount of wear to the mesh along the bottom where the bag would have come into contact with the surface it was placed on.
Overall, in very nice condition for a 90 year old piece!
