Corporate logos constantly have to adapt in order to survive. In the case of the Shell oil company this results in an image that ironically resembles the ones we know from the biology classes.
Still one wonders how the biomimicmarketing of the seashell came into existence. The reason is rather straightforward: "The word 'Shell' first appeared in 1891, as the trade mark for kerosene being shipped to the Far East by Marcus Samuel and Company. This small London business dealt originally in antiques, curios and oriental seashells."
Perhaps in due time, when all the oil is gone, the multinational could return to selling antiques, curios and oriental seashells again. No?
