It was a guess. :) I'd expect it to be in the range of 20 to maybe 50 USD depending on the amount of pages. And I wanted to have a comparatively low price in contrast to the price for flight and everything else. I think most of the HC editions are going fairly well. They fit better upright into any bookshelf and are more sturdy on long term (or if you happen to have children and they start reading ElfQuest). So I guess maybe more people would have bought that than the relatively limited number in terms of audience that can make it to an exhibition / convention like that.
