To naswer yer questions Corey...
Was in the running til the last few seconds for the Sal Manilla proto at over $1100, but I got sniped... Though the person who won that prototype was a fellow Palisades forum member at the time, someone who went by the screen name MuppetNut.
As far as the SS figures... There were two fully-painted versions of the facade, and they were snatched on eBay for $2500 and $3500 respectively. They both came with the Oscar figure, and the more expensive one was cased in it's own shipping box which Ken willingly sold off. Are there carded final version figures? Well, the ones I got could be considered carded... Except that the clamshells weren't sealed off (just held together by removable staples) and there were unmarked plastic paper inserts. Rully unsure if there are any others left though, there might be a very small number, as another forum member also has a final fully-painted Two-Headed Monster figure.
Hope this helps, LMK if you have any other questions.
