being someone who spent the last 5 years doing this, I can certainly tell you it's not.
I also happen to know my shit.
Let me illustrate it.
The textures are not the originals, they are good cloning brush work (and definitely painstaking work) but they are just not the originals (with one exception - the artifact, which is correct, but it's cropped quite a bit unfortunately.
In the case of the artifact frame, as you can see, the background included fits over if it's sized a little down, it misses the information on the edges - I've stroked and superimposed the background in that template:
For the blue, this is the best image of the background available from card scans. On the right, the background. I think this one is quite obvious. The lower part kinda fits, the rest is pretty much something else.
Convinced ?
I'll try to do better frames, I believe I can in this case. I just want to help and wanted better card images, I don't give a rat's ass about who's right&wrong.
