I'm not certain about the Bon Bon series, either, but it was the closest in the 2000 Catalogue that I could find. I went and dug out my 1994 Catalogue, and it's not quite there either, although the one in the link provided by Christine is there. (The number on the linked piece is 89060, as the 9 has been read as as 7, which makes no sense). For me, the colours, the lines on the piece, and the shape that point towards Bon Bon. However, the Bon Bon jugs that are pictured in the 1994 and 2002 catalogues have pouring spouts, not a rim of coloured glass at the mouth.
The 1994 Catalogues has quite a few small pieces, labelled either mini or miniature that are shown as part of the series.
Daniel: I think that you're right about "Artist Collection" being partly based on colour, at least to begin with. In the 1986 catalogue there is a separate section near the end of the book headed "Artistic Collection." All the pieces are by Vallien or Hydman-Vallien. They're described as "a little more adventurous, more avant-garde." By the time of the 2002 catalogue, everything is included in "The Artistic Collection." Nine of the 41 series shown in the the 2002 "Artist Collection Catalogue" are clear. However the series were categorized in the catalogues, I don't know which ones had "Art. Coll" engraved on the bottom.
It's a lovely little piece whatever, Rose. And the price still can't be beat.
