Anne’s Mystery Trinket Set 15http://www.glasstrinketsets.com/cms15/index.php?option=com_content&view=article&id=165:mystery-set-15&catid=28:mysteries&Itemid=52
is usually seen with a distinctive floral tray, candleticks with a large floral boss to the stem, a similar large floral boss as trinket pot lid finial, and smaller floral decoration to the pot body (as in photo 1).
Now I have come across two separate sets in clear amber glass, both with the characteristic 8-sided Mystery Set 15 tray, but both with variant pots. Both sets have trinket pots with a tri-lobed lanceolate finial instead of the large floral boss, The pot bodies still have floral decoration, but the flower heads are now smaller and more discrete.
One amber set also has a ringholder that appears to be the same as that with Anne’s ‘original’ Mystery Set 15.
The other amber set also comes with a set of branched ‘double-holder’ candlesticks which may, of course, not necessarily have been standard to the set (though the colour match is good).
