Always loved this set. I think it's mostly from nostalgia. This was a year that was plentiful in my neighborhood in the early 80's. It was vintage to me.
Looking over the set, it's kind of boring from a photo viewpoint. Good photos, just the same headshot, pose, or bat rack shot throughout the set.

This card is only special because of my childhood memories. A vintage card of Sutton before the fro.

Uh, Norm you should check your fly.

Is there an earlier shot of a player signing autographs on a Topps card?

It does have the rookie trophy

My favorite player as a kid on his first solo Topps card.
Honorable Mentions (these are probably better choices, but I want to choose other years for them, that damn 2 card limit per player):
