Try taking a picture outside during the day but, not in direct sunlight. Also, back away about 18-24"s. I assume you have some type of photo editing software to resize the picture. If so, it may have a "crop" feature that will let you get a close-up to post. If not, you can e-mail me your pics and I will do it for you.
It looks to me like a lady holding a bunch of flowers. Maybe I have been looking at to many buttons. It certainly is a nice find and I am sure very collectible

I think it is most likely a lid from a Victorian vanity set. There appears to be a "lip" or crimp on the underside of it, right? If that's the case, I'm pretty sure that's what you've got. Many of them were made of ornately decorated silver.
