MAF mechanics, aesthetics and framework

I have decided on choosing the game Cluedo, with  a 70s retro theme.  Mechanics and theming would revolve around the Fleetwood mac scandal that occurred in the 70s.

Hippie, Retro and Dreamy are words I used to describe the desired aesthetic for my game without using the term “70s”

Since Cluedo boards are very detailed, using the term “70s” is not defined enough in description, therefore these words would narrow down my reference research for artistic influence for the game board.
