I would think that since most collectors in europe have to pick and choose, much more than us, they would show their best?
I have seen, in person a couple of european collections and they look like american collections, in the sense, good and not so good
I have a couple of not so nice pieces, I am disinclined to show them on the forum?
I would think most collectors are the same way, as the vast majority of people here on the forum, have never shown anything they own.
