Antique Plate

[birdog63]

I have attached two photos of a plate that belonged to my mother.  I acquired it when she passed away.  I know she had been in possession of the plate for over 30 years.
I am interested in any information anyone may have relative to the plate.  I would like to know who or where the plate was made or how I can find out more information.  If someone knows the approximate age of the plate that would be helpful.  Also should I take it to a local dealer to get additional information.

Thank you for any assistance provided.
