It could be the expected sale price indeed.
I do see that prices have dropped since the last 5-10 years.
I always thought it would pretty much still have the same value.
Maybe it's not. Hoping it'll come back one day.
And till that day I'll try to buy as much as financially possible

And it's true that many items have been sold as a combined lot,
but I don't think of it as 'add ons' because there are quite astonishing pieces amongst it.
I don't know if I'm allowed to place links to auctions here.
(If not I'll remove it). But it's items like this that just don't make a sell.
This is a stunning set of 3 art glass pieces, made by the Romanian glassblower
"Tubi Vasile Vadan". It's fused glass with iridiscent copper/bronze.
To me this is quite exclusive. What do you guys think about this for an example?
Still has a few days to go. But no bids yet.
