Rarely seen as big a deal as I believe it to be, but the Kinks never had a logo. The Beatles had the drop T, The Who had the male gender symbol, The Stones were slow, but their tongue was the most iconic of all. If the K in the name Kinks was to look like a boot - it was a poor design, and they didn't stick with it. As insignificant as it may seem, I think this really hurt their ability to 'stick' with a casual fan. The Kinks would always be awful at branding - and even worse at hiring competent management who would recognize the power of a logo.
