I think the 1st edition symbol being like that is a printing error.
But its a printing error from someone who is creating fakes.
This is clear proof of how well they are creating fakes though as I think the ones doing it (it might just be 1 guy for all I know) are the same ones creating fake 1st edition base cards like Charizard which I think gets put on ebay a good bit, after recently linking 2 auctions of Charizards I thought were fakes, those auctions in no time vanished off the site.
I think the Raichu is a fake, the colorization is too dark and the text is not the same as originals, its very clear cut IMO. The Energy symbol the bolt is too thin also.
I also have reason to believe the placement of the 1st edition stamp is an indication someone is using a printing machine like the one WOTC has or any card manufacturer.
I will throw out the possibility someone from a card printing company is faking them on their free time to, some of them have not gotten the card stock right, some will get it close enough. I think this fake is pretty good, but i also think I have seen better fakes.
