This question comes up from time to time, and I typically give the same answer: 1935 Goudey
It's an American Goudey gum card from his playing days and can still be had for a good price. The prices on these have gone up over the last couple of years (just like everything else) but you can still grab a PSA/SGC 1 grade for under $1000.
The fact that he's not listed as a Yankee, and he shares the card with three other Braves are the contributing factors that keep this card priced lower (although according to the pop reports, there are less of these than the 1933s...especially with specific back images).
I picked this "beauty" up about a year ago for $300. Having a nail hole through the middle also helps keep the price down
