The Reidel piece I saw was like your face box.
It was in the passing on an ebay search - and I didn't make a note of the listing. I looked at the two images together, yours and the listing at the time, and decided there was simply too much difference. So sorry. :pb:
It was a box, it had a funny face on it - but it didn't have the same expressiveness, it didn't have glass fibre inclusions (which is what I'm convinced your box has - they're far too like the Benny Mozfeldt glass fibre inclusions I had a few examples of) and it didn't have any colour.
Probably a bit of a red herring mentioning it - although it did cross my mind that their box might be a "tribute" to the designer of yours.
