The Nostalgia Factor

Thanks!

I'm new to the forum. I was directed here by somebody in the community. I was recently gifted a complete Atari 5200 console in box. The box contains a "Free Pac-Man" sticker in the top left corner. I know those are pretty common, however, the sticker on my box is green and not blue. Its phrasing is also different than the blue sticker boxes I have seen online. It also contains a "Sears" sale sticker. Could someone explain the variation, its rarity, etc? I have no plans on selling, I was just inquiring about the story behind this particular variant (sticker color primarily). Thanks. See below:
