What is this painting called

I have a few pieces like this. Flowers painted on a slick black metal. Maybe tin? Is there a name for paintings such as this? Measures 8x10

 

I guess you'd call it toleware.

 

Toleware as above.

Thank you guys that helped me identify half a dozen things lol

 

Interesting frame with a nod to aestheticism.

 

More interesting than what it displays.

Hmm interesting perhaps I'll try targeting frame buyers instead of focusing on the painting. Thanks for the feedback!
