Vintage Huge 1972 Dart Industries Wall Decor Plaque- Center in Wall Arrangement

Huge wall plaque in taupe, sage green, and lilac with gold accents. I didn’t paint it but it looks like it might not be original, but it’s well done so I’m not certain. Two areas of paint have an Aurora borealis effect (not sure why) and a couple small areas with cracked paint. See the last two pictures. Not perfect but really charming! Questions?
