The best Elvis Fan Club magazine published during Elvis´ lifetime was without a doubt Rocky Barra´s STRICTLY ELVIS.
He started the club (and the magazine) in 1968, just before Elvis reclaimed his throne. Sadly enough I do not own the first three issues myself, but I have scanned the numbers 4 and 5, with more issues coming up soon (I hope).
