Not necessarily crazy. Many collectors own posters that they have no intention of displaying. I sold a THUNDERBALL 24 to a collector that had it backed and it is up in his work area, a large space to be sure. We have sold 24 sheets to theaters, bars, law firms, restaurants and museums, as well as individuals. For completists who want everything on a film, 24 sheets are often the last poster they acquire - because they are scarce in the overall scheme of things.
