Huge chrysanthemums door or wall plaque, vintage plastic Burwood or Syroco?

Gorgeous huge painted shaggy mums wall art plaque, 60s or 70s vintage, we think? This isn't marked that we could see, but looks like a Burwood / Homco or Syroco piece to us, heavy plastic with metallic gold.

This measures 48" long overall, and has a hanger at the back for hanging. There are few small rub marks to the color painted area, this looks very nice overall.
