Crain's moves out-historic home comes down?

Crain Communications moved out of their long-time home at 747 North Rush Street back in 2001; throughout the move, they trumpeted how they were moving to the historic and newly-renovated London Guarantee Building over on Wacker, saving it from abandonment. Very soon, their equally historic Rush offices were slotted for demolition, confirming my theory that unless a building is landmarked, its future in Chicago is cloudy. Not only that, it seems hypocritical to tout this move as if they are preservers of architecture. Since 2001, the building has been "marketed" as for rent, all the while just sitting there with the infamous public notice sign (from 2002), signaling its impending demolition. All the while, happy tourists eat at Giordano's, a planned new tenant of the likely personality-less skyscraper that will replace these structures. If you look closely at the photo below, you will see the shadow of the sign for the Chicago Film Laboratory. Perhaps this was the home of one of the pioneers of the Chicago film industry? Mr. Archibleckture wonders what will come of these mothballed structures? Will a miracle happen, and another use found for them? I happen to think the buildings should be converted to condos.

Love, Mr. Archibleckture
