You will note that the seller refers to my article on these paperweights in the 2006 PCC Newsletter. I have six from this factory, and have seen images of another 3 or 4. The designs include concentrics, scrambles, a harlequin, and sodden snow and colour grounds. Most of them are untidy - for example the eBay one. The weights are relatively large (65mm - 80 mm diameter). So there are very few around, but I suspect there are more that are - as yet - unidentifed. I have attached images of three.
I am still trying to find out where they were made, and when. Of the small number known, about half have turned up in the UK, the others in Germany and France. A very poor blue ground went through Boisgirard with the attribution 'Clichy Apert Frères' : I asked why, and what evidence was there for this - and got no reply. There is an ice pick flower known with Apert Frères on it, advertising their factory - but I don't think there is any evidence to link them with these 'starfish' paperweights.
My feeling is that these are probably French or Belgian, and maybe made after the classic French weights, which they were trying to copy, with limited success.
