Masters of Sex season three TV billboards...

Time to twist and shout with joy as Masters of Sex is back for a third saucy season, as the series moves into the swinging Sixties.

Michael Sheen and Lizzy Caplan are back as real-life human sexuality pioneers, 'William Masters' and 'Virginia Johnson', joined in this threesome by Caitlin FitzGerald as William's wife 'Libby Masters'. As they say three's a crowd, that is, unless it's a ménage à trois.

These Twister game inspired billboards for the third season of the Showtime drama were snapped along Ventura Boulevard, Santa Monica Boulevard and La Cienega Boulevard from July 4 to July 9, 2015.

If you're a fan of the show, be sure to check out the previous season promo billboards for Masters of Sex, which considering the subject matter are always tastefully done.
