This was Wei-Hwa Huang's IPP28 exchange puzzle. The aim is to match up five pairs among the ten pieces (two are shown in the photo) so all the pieces can nest in the cylindrical container. The problem can be interpreted in terms of a connectivity graph.
Top has on it "(c) Wei-Hwa & Oskar", the latter referring to Oskar van Deventer.
