I started collecting baseball cards in 1967 - not at the start of the season, but sometime in May as I recall. I think Topps was into their 2nd or 3rd series by that time, but through trading with other kids, I was able to play catch-up and get all the earlier cards I missed (except for the Cardinals team).
As best as I can remember, these were my favorite 1967 cards at that time:
The top row of players is self-explanatory.
In 1967, Topps made 13 multi-player cards. These 3 were my favorites. (I was a Phillies' fan, but I'm not sure why I liked the other two cards over all the rest.)
Chris Short and Johnny Callison were my two favorite Phillies players. I started following that team the same month I began collecting cards.
Jim Palmer's card came along in the 4th or 5th series, as I recall. I became a big Palmer fan when I got this card. I don't remember why - he missed almost all of the 1967 season, and I wasn't following the Orioles. Maybe it was because the Orioles had just won the World Series in '66, and here was a good, young pitcher named "Jim"?
Anyway, on one of the T-shirts I had bought from a local discount store (those surplus high school gym shirts with various schools' names on the front, that you could pick up for a dollar or so) I had written a big number "22" with a Magic Marker. (As I'm typing this, I am remembering the kid in the Vince Papale movie "Invincible", who made the number "83" on his shirt with bits of duct tape.)
One of my friends who was a Cowboys' fan just assumed it was in reference to Bob Hayes. Ha!
So I had become a Jim Palmer fan before his great comeback in 1969. For that, I feel like I got in on the ground floor. LOL
