The "am" Stands for About a Million.
Both of these self-promo ads appeared in yesterday's (January 30th) edition of free daily rag amNew York. The one on the left, on page 24. The one on the right, page 38. Such an exact figure, that first one. Yet, it's contradicted 14 pages later. Perhaps, the ad on the right was placed by main competitor Metro New York? Or perhaps, amNew York is playing loose with advertisers' money.
(UPDATE: amNew York cops to the fuckup in the comments.)
