Sega's Game Gear was a reasonably successful, if short-lived, competitor to the Nintendo GameBoy. Its library was sizeable, with quite a few solid and interesting games, including some unique titles based on enduring Sega and third-party franchises.
And there were lots of accessories, though this mid-1990s ad glosses over the details, instead devoting its two-page magazine spread to bizarre art design featuring a bored young man with giant fingers growing out of his head. Or, perhaps, an excited, disembodied hand with a miniature face grafted on at the wrist. Any way you slice it, it's just weird:
If it's not SEGA, you lose... your mind, apparently, or at least your sense of design and much of the intended commercial message.
But, ahhhh, those were the days.
When Photoshop was young, and all the world its page.
