I believe they are fake. There were a few things supporting this but I can't remember many of them off the top of my head.
One was that, if you look on the starter evo page, on the left, you will notice that the page before it doesn't match up in the least bit and looks as though it was just thrown there to make it look like it wasn't a single page.
Another was on the same page. If you look at the right, you'll see the shading changes in what I'm assuming was meant to look like a curve for the center of the magazine. You may notice that the grass starter's evo, the area arounf his nose, does not change in terms of shading on the page.
Lastly, the fire monkey guy's shading under his head seems to be inconsistent with the grass ones. The grass monkey uses only 1 shade where as the fire guy uses two. A small detail but I think it's odd that, if it was truly official, the number of shades would change.
