Great thread.

Mine is Drop-a-Card (or maybe Pop-a-Card). It was the very first pin I played and even though it's a memory from early childhood I clearly remember the distinct bg and pf artwork. My dad took me to play it in the rec center in the tiny town in PA where my folks grew up, Emporium, when we were visiting.

Years ago I bought a major project D-A-C that's still in my garage (bg stored inside). I should've gone for a nice working P-A-C that was for sale on pinside in remote north central PA not far from Emporium -- wouldn't it be an amazing coincidence if that was the actual machine that I first played around 1975?!
