Two men pose together for a magazine cover. The man on the left has dark hair and a beard, smiling widely with his eyes closed. The man on the right has short graying hair and glasses, smiling at the camera. They both wear dark blazers over light tops. "BUSINESS IN CALGARY" appears in large red letters at the top along with "and CALGARY COMMERCE magazine" and "DECEMBER 2000 $3.50". Large text reads "Calgarians of the Year" with "Hatim Zaghloul and Michel Fattouche" and "New economy pioneers" below them.
