Longstanding public Steelers / Green Bay matchup prediction

I first saw these flags posted to a deck in Regent Square in 2004, and thought, "that's respectable".  I'd often wonder, as I passed the flags on my way to work, if there were multiple residents of this apartment who hailed from both cities, or if it was a couple with split allegiances; or if it was a Pittsburgher just putting it out there that these are the two respectable teams in the league.  Whatever the reason and whoever they are, these people have been predicting today's Super Bowl matchup for at least 7 years.

Respect to Green Bay

GO STILLERS!!!
