Of the estimated four billion cups of Starbucks coffee that are sold in any given year, most caffeine hounds are probably chugging them down so quickly that they barely even look at the logo on the cup. But if they did, they’d notice a couple of things: yes, that is a mermaid, and no, the coffee company’s name is nowhere to be found. Though the siren has been the key image on all of Starbucks’ products since the company’s founding in 1971, she’s had a few makeovers over the years—most notably in 1992. The image was zoomed in to only include her top half. Then, again in 2011, the company name was removed altogether.
