Official Car of the.....

Anyone know what the Official Car of the Atlanta Braves was in 1971??? I'm assuming that's Atlanta Stadium (later Atlanta-Fulton County Stadium) in the background as Mr Aaron trots around the bases.
But it could be spring training too.... who knows?
I got this wonderful card awhile back from our friend Jim, of the famous GCRL blog. Apparently he was at a card show and posted on his blog via Blackberry, asking whether anyone wanted anything. I asked for a '56 Topps Hank Aaron. (I didn't want to be greedy and ask for his '54 RC)
This is what I got in the mail shortly after.
I'll take it. Close counts in hand grenades, horseshoes, and Hank Aaron card collecting....
