Need help identifying my art pottery vase

I have this large 2 handled vase, it is yellow with green patterns that are almost primitive, decorated with Suns, moons flowers and birds that are childlike Picasso type. There are 3 green protrusions on the vase. The are no markings on the underside. I've done loads of research but cannot find out its age, origin or manufacturer. Any help would be appreciated.

Thanks

Jan
