Hydrangea Flowers Painted Slate Nostalgia

Old fashioned looking wall plaque that you can hang or prop on an easel. Pink hydrangea flowers & green leafing with accents of Peridot green crystal rhinestones in random placement. There is a friendly & sincere postcard with cursive English writing & postal stampings. I'm not sure what decorative style this would be considered. I took several photos showing different backgrounds and each variation makes a different portion of this picture pop out. Please comment if you have any questions.
