The art of woodrails just gets me every time, the geometry of the 30's  - 40's then the pin up girls of the 40's -  50's,

Favourite EM period to play is 60's, both Willaims and Gottlieb were making some crackers here.

I can quite happily miss the whole of the 70's and jump straight to Gottlieb sys80 + and early 80's Bally
