Source Unknown Antique Art Nouveau Silver Plated 10" Hand Vanity Mirror Victorian Design 1905

In excellent preloved condition no chips or cracks to mirror and has some mild oxidation. I have not cleaned as some people like that look. I'm unsure of the brand, the only marking I was able to find is Pat. June 13, 1905. I'm assuming its silver plated. It weights 12 oz. Please feel free to ask any questions.
