Agamemnon Triforce

I've noticed some alternate box covers for Frogger. There's the original Parker Bothers, silver cover and then there seems to be a second version that looks like the silver Atari branded copies. Did Atari acquire the rights to publish Frogger and make their own boxes? Are these just competent photoshop jobs? A few of the Atari branded ones I've seen have price stickers on them. Does anyone have an idea of what's up with that?
