The one on the extreme right was released months ago when it announced that Wake would be defending his title on July 21st. At that point there was no opponent named and no undercard, at all. The only thing we knew was that Wake would be in action.
Several months later Wake's opponent was named and we got the middle poster telling us that Wake would be fighting Lee.
More recently we got the third poster, the one on the left. By now the undercard was sorted and the undercard fighters were all added to the poster .
It's interesting to see the development of the posters and we'll admit the newest one is by far the best and gives the impression of the bout being a great one, a view we share.
