Found this little gem the other day. A retro orange and brown divided serving dish by EMSA, West Germany.
EMSA was founded in 1949 by Franz Wulf. Their first successful plastic product was a butterfly shaped coffeepot drip catcher in 1953. They started producing plant care items and then tableware. The company is still in business today.
I've only found one other piece by EMSA. It was a covered butter dish in similar colors.
