Vintage handmade plaster wall art floral chalkware

Isn't this cool? This art piece makes an oval frame for a bright vase of flowers. I can only find one tiny chip, see photos. It has the original price tag on the back and a built in hanging hook. It's made of plaster and sprayed in colors, the way chalkware was made. Please examine the photos closely as they are part of the description and have the measurements.
