I collected baseball cards from when I was about 6 years old (1968) until the early 80s, when all the middle-aged baby boomers came in with their money, tried to recapture their youths, boomed prices up so you needed to have "expert appraisers" rating the condition of cards to "protect investments" and completely ruined the hobby. Here are my all-time favorite cards, though, most of which I got the old fashioned way: out of wax packs with bubble gum, the rest from shoe boxes at collectors conventions in the days when the biggest baseball card show in New York was held in the basement of a church.
For a real baseball flavor, the music is by a hero of my childhood, Denny McLain, at the console of the mighty Hammond Organ from his 1968 LPs "Denny McLain at the Mighty Hammond X-77 Organ: The Detroit Tigers Superstar Swings with Today's Hits" and "Denny McLain in Las Vegas". It's too bad Denny didn't confine his swinging to the ball field or the console of the Mighty Hammond organ. He'd be in the hall-of-fame today.
