Jane Jensen's new production studio is having a kickstarter, and they have added a new reward to the 500$ award tier: original sketches made for GK1 production, back in the early nineties! Apparently someone saved these from a dumpser right after Sierra closedm its doors. You can see some of these in here: http://www.kickstarter.com/projects/1005365109/jane-jensens-pinkerton-road-2012-2013-csg/posts
