Danish modern vintage wood salad set, round ball serving bowl & salad bowls

Vintage Heller Ware wood salad set with great retro shape - we love the danish mod style ball bowl, and the four little individual bowls. It's marked Taiwan, so it's probably late 70s or early 80s vintage.

The ball stands 6" tall overall, and has a wide opening at the side / top. There's a couple of tiny chips to the spoon and serving bowl, as shown below - but the set as a whole looks good, without a lot of wear or scratching to the finish.
