I am not sure but I think this is the first time that even the release of a boxing fight's official poster has made its way to the big news outlets, but yes it has. The Floyd Mayweather vs Manny Pacquiao mega fight just got its promotional poster released for their upcoming bout scheduled to take place on May 2, 2015 in Las Vegas, Nevada USA. Check it out below.
I have seen previous posters from Pacman's fights and most or all of them have fancy titles but this one seems to be very simple by just putting the fighters' name side-by-side. There's even no "vs" in the middle. That's something new to me.
One of the highlights of Money-Pacman fight is a no-rematch agreement (at least the last time I checked) and I just recently learned that even placing fighters' name as to whose name will be mentioned first or not when it comes to marketing materials is also part of the deal. See for example on this poster, Mayweather was written first before Pacquiao. I also have just read that at the fight night, it was also agreed upon that Mayweather will be the last to be called to the ring. I didn't really know that those things are also big deals in this industry.
