OK, I have just perused about 500 google images, and looked at every eBay auction for Pokemon yellow currently available...I was bored.
NONE have anything close to that. I also looked and couldn't find any information about Nintendo re-releasing it. Some copies have a -1 next to USA on the side label, but that is the only difference. I have also looked at other Pokemon labels for other games to compare. Even as they progress, they never have just black text depicting the version, they never have part of the title cut off and (as said before) they never had that fuzzy "drawn" feel to them. The game may be legit, or it may not be. But the label is fake. And if you bought that, new, sealed, then someone went through ALOT to replace a label and reseal the box before returning it to Electronics Boutique, Walmart, Toys R Us or where ever in 1999.
Sorry buddy
