Edit: I misunderstood your question and tone, sorry, but everything below still stands!

They're temporary buildings made of wood, plaster of Paris, and cement, built here as an 1898 World's Fair.

"You are being lied to" heavily implies that the history of Omaha is being glossed over somehow (perhaps with respect to the Civil War? though it was a Union state, and the photo decades later than the war), and that this was the architectural style and decadence of Omaha. You are being lied to, every day, by politicians and advertisers and corporations - but the photo has no relevance to this. These buildings are little more than façades.
