His latest showcase is a Puma Uruguay home shirt prototype that has produced spectacular numbers on Twitter - but why was it not approved for use?
Disapproved Puma Uruguay 2016 Home Shirt
The shirt is very similar to what Puma ended up releasing as the Uruguay 2016 Copa America home shirt - with one exception.

The sleeves of the prototype feature a black-and-gold stripe pattern that is nowhere to be found on the shirt that ended up being released.
And this detail is almost certainly the reason it was never approved as black and yellow stripes are closely connected to one of Uruguay's biggest clubs, Peñarol. Puma and the federation in particular did not want to offend the supports of other Uruguayan clubs such as Nacional, Peñarol's big rivals.
