Starbucks Logo

The coffee chain logo features a siren from Greek mythology. However, it turns out, sirens did a lot more than use their signing voice to lure sailors to their deaths. She is holding up her two fish-tails in order to not-so-subtly expose her crotch. THAT is what Starbucks chose to add to its corporate logo…

Unocal 76 Logo

The Union Oil Company of California was founded by Thomas Bard, and Wallace Hardison, and Lyman Stewart in 1890.
The 76 brand was created in 1932 at the suggestion of Robert Matthews. It’s a reference to the Spirit of 76, which coincidently was the octane rating for the company’s high-performance gasoline.
