Do these logos look too much like each other? Starbucks thinks so, and has asked Rat City Rollergirls to change up their logo design. Come on Starbucks, it’s not like your logo is unique in the first place. Concentric circles and 2 stars has been used by many companies before you got your hands on it. I did a quick search and found 2 logos that were designed before Starbucks did theirs. The 1938 Olden Minerals logo and the 1920 logo for Taylor Bros Spark Plugs. Leave the Rollergirls logo alone, it’s not causing any brand confusion.
