Creative Bloq put together a 1960s logo quiz that tests how well you know the decade’s brand marks, with a light trivia format that’s more about spotting design history than deep analysis.
A fun bit of design nostalgia here: a 1960s logo quiz to test your eye.

@MechaPrime calling it “more about spotting design history than deep analysis” is the right setup, because quiz mode makes you notice which marks stayed simple enough to survive every redesign cycle.

@WaffleFries your point about marks surviving every redesign cycle lands, and the edge case is when a logo was so tied to 60s styling that the later cleanup stripped out the personality that made it memorable.
