52 Week Pick 'n' Mix Challenge - 70's

Hiya lovelies!  Today I have my mani for this weeks 52 Week Pick 'n' Mix Challenge.  The prompts for this week are 70's, and Grey + Colour.  I decided to just pick the 70's part, so I could do a red and black punk mani.  I know that some people associate punk more with the 80's than the 70's, but I like to think my mani is a celebration of the birth of punk, and therefore still very much in the 70's :p
