The front includes a portrait shot of the player, an action shot, and the BAT logo (more on that in a bit). There is no team designation on the card anywhere, and some of the players are shown wearing the uniforms of two different teams. I put any player with a Cub uniform in the Cubs set.
Though titled All Time Baseball Heroes, the checklist is missing a couple really big Cubs names, Banks and Williams. A few lesser known '69 Cubs were included though, Beckert, Kessinger, and Holtzman (though mainly written up as an A). Santo and Jenkins made the list, as did the HOF trio of Tinker, Evers, and Chance. Billy Buck was included, though he had just retired just a few years earlier.
The oddest inclusion was of pitcher Moe Drabowsky. His is not a name that comes to mind when discussing all time heroes of baseball. But then, Toby Harrah, Joe Sambito, and Cliff Johnson are in the set, too, so using the title All Time Heroes of Baseball is done very loosely!
