TCB is Elvis' favorite logo and all of his inner circle friends had necklaces with "TCB" on them. This stands for Taking Care of Business. The lightening bolt was his signature symbol. Elvis even had this logo emblazoned on his airplane/The Lisa Marie. For his lady friends he had necklaces made for them with "TLC" meaning Tender Loving Care.
Clothier to the King also has socks, shoes, hats, t-shirts and polos all with this signature logo so everyone can channel their inner Elvis and feel included in his "Memphis Mafia".
