All:
At the end of this auction everybody is going to see that the first bidder on the Irish Goldfinger quad put a huge bid - probably at least $3,500 - on this poster. Furthermore, several other "fat wallet" collectors and dealers - most or all of whom have no idea this forum exists - are going to come out at the end and push the price well past $4,000. All this talk about getting it for a steal or being "robbed" of the opportunity to get it for $1,500 was just a pipe dream. James Bond posters always get lots of attention on Ebay and this particular seller is selling a boatload of James Bond posters, so this poster realistically was never going to "slip under the radar."
So whatever theoretical arguments - which have been endlessly rehashed here - against discussing pending auctions have no applicability to this particular poster.
By the way in the last four hours, another bidder has entered the arena and pushed the first bidder's bid up to $1,600.
I don't know why you keep linking bid amounts to justifying outing an auction. I've set my next snipe to $2,700. If outing my auction results in me paying an additional $100 or more I would be mad. $100 is still a lot of money, especially if I purchase hoping to resell it again covering my costs. $100, say, spent on a birthday gift for someone would likely really make their day, the amount is still a lot to me.
I have many posters I spent more than $4000 on. Your arbitrary limit is just that, your limit, not others. By defining a limit, you though are acknowledging that it is inconsiderate to be outing them. Like I said out frankies or metropolis poster type items in high profile auctions, where the spotlight is already on them. And if you are going to out an auction, as it can only push up not down the final price, at the same time highlight an auction you are seriously bidding on, for us to see too.
by the way.. as an addendum to this whole conversation:
I don't know why, but movie poster collectors are the ONLY people I ever hear arguing that people should not post auctions in progress and (for instance) the CGC messaging boards which boast 10s of thousands of forum members (I think it's 60k alone in comics and more in coins) regularly post in-progress auctions going on.
The reason: because these collectors are in general agreement that posting information is what forums are all about and any information posted that helps even one person is something that helps the hobby in general.
In comics, such a perspective is unique as for teh most part, the hobby is made up of many very greedy people whose own self-interest is way more important than any altruistic pursuit
These really helpful people I also assume graciously highlight to the community current auction items they themselves have unearthed and are lusting over and bidding on.
