Funny thread !
For me it is Pistol Poker.
The heart of my little collection are rare machines, specially from Alvin G.
So I collected within the last 15 years
Garage Band
Mystery Castle
Pistol Poker
USA Football
Dinosaur Egg
Together this is a very nice collection not every one in my area has. But .. PP is a brong machine. USA Football the same ... but they have to stand together
For nearly a year I gave my Alvin G.´s to a pinball museum to have some space. meanwhile sold most other machines and .. back to the roots with all the Alvin G.´s in my gameroom
