Among other stuff that is currently being auctioned off by Skyway Model Shop of Renton, Washington is this 1/72nd scale Boeing 747 display model from the late 60's or early 70's. It's got a cutaway fuselage (covered with clear) to show the interior and is in Boeing livery. It's a model of the prototype (N7470) and is a serious collector's item already. If you're into airlines and airliners, I strongly suggest checking out this auction:
