Yes, presse-papiers = paperweights
I have amended your link entry for a search on "presse-papiers" rather than "maes" - but even with that, it seems to now want to start at page 521.
It is an interesting entry and I immediately wondered if the jurors had foreseen the modern influences of mass production from China! But the main reference seems to be to a generic "mille fiori style of work" of which paperweights were a part and were an adaption of the "style of work".
