That may be one of the first questions asked when fans reflect on the annals of mixed martial arts history. After all, it's not every day you break a North American attendance record and sell 55,000 tickets to a UFC event.
But that's exactly what happened when Canada's most popular athlete was booked for the promotion's debut in "The Centre of the Universe."
And now you have something to remember it by.
Round 5 collectibles will commemorate this historical event with a Georges St. Pierre Special Edition Collectible, limited to 1,000 copies on a first come, first served basis, featuring "Rush" adorned with his authentic walkout Gi from UFC 94 complete with die-cast championship belt.
There's just one catch.
This Round 5 exclusive will only be available at the UFC Fan Expo in Toronto at the Direct Energy Centre from April 29 right up until fight time on April 30 to coincide with the "St. Pierre vs. Shields" pay-per-view.
But don't expect them to last that long.
Previous Round 5 collectibles of such limited quantity have been known to sell in excess of $300. That's a sweet little investment, considering The Georges St. Pierre Special Edition Collectible, which comes in commemorative UFC Fan Expo packaging to coordinate with its release, retails for just $25.
In short, if you want to get your hands on this piece of mixed martial arts history, "Rush" over to the UFC Fan Expo on April 29 for this exclusive addition to your collection of UFC memorabilia.
Before it's too late.
