WWE's business success is all about promoting pay per view buys and arena ticket sales. One way the company sells their shows, is through production of engaging event posters that catches fan interest. We've witnessed many great pay per view posters over the years. In time and with the aid of nostalgia, many of these posters have turned into iconic masterpieces. If you're a wrestling fan, then a vintage WWF poster can represent a collector piece of artwork. In looking back at these classic posters, we decided to focus on the WWF's most important period: The Attitude Era. This was the time when men like The Rock, Triple H and Stone Cold Steve Austin made every pay per view a must watch show. The story-telling drama was so good and the athletic matches even more thrilling. Then you had all the sexiness of the divas and the violence of the gimmick matches. It really was a special time to be a fan. We've classified 'The Attitude Era' as Survivor Series 1997 until WrestleMania X-Seven. This was fitting because Survivor Series was the night that Vince McMahon 'screwed' Bret Hart and ushered in the Mr McMahon character. A month later and McMahon made his WWF Attitude speech that officially started the era. The ending of the era was in April 2001, the night when Stone Cold Steve Austin turned heel on The Rock. It was a creative finality to what had been a glorious few years. Here's the twenty greatest posters from that time.
