The mistake was on page one in big, red font.

Pressroom employee J. Michael Klop told the media blog JimRomenesko.com that printing press workers noticed the headline early on and alerted the editorial team, correctly believing it to be a mistake and not a nostalgic look back on the year Barack Obama was re-elected and London hosted the Olympics.

"There was nobody there who was willing to make a decision to stop the run and remake the page," Klop said. "Finally, after finishing the run, there was a call back from downtown saying to wait for a new set of plates… as they were going to toss the entire 20,000 and rerun the full draw."

The paper's editor, Kathy Best, told the blog that the "crazy holiday weekend schedule" was to blame for the "glaring error."

"Because the press run only lasts about 30 minutes, we didn't send a corrected page in time to catch the run," Best said. "Not a great day, including missing a chance to say stop the presses."
