It hasn't been that long since Jay Z was throwin up the Roc as a young Hov. For New York magazine's annual yesteryear issue, the kid version of the rapper-mogul appears in a throwback photo of a 29-year-old Jay, rocking a red cap and a leather jacket, in 1997. The issue, which celebrates the past century of New York music, has seven other covers on deck, including ones with Notorious B.I.G., Madonna and Barbra Streisand. It also contains the Encyclopedia of New York Pop Music. Cop your copies as it hits stands today.
