Those colors are very old-school Barca. Even the stripes on the sleeves don't look that bad when they gradually widen like that. Yellow QA logo would be better, but we'll see.
I'm not sure about that, but just to go back to the original picture, that QA logo does seem edited onto the photo. It doesn't follow the wrinkle of the shirt.
I saw it in the stores, as well. Or maybe it was something very similar, I'm not sure. But it was definitely an old-school Barca shirt made by Nike. Not really a jersey by today's standard, just a regular cotton shirt.
