I'm not sure if they have early Aaron images but the best place to order high quality MLB photos is photofile.com. All of their photos are licensed images and they currently have free shipping until the end of the month when you spend $15 or more.
Check out this site for lots of great photos and obscure shots. The photographer covered all Cubs and Whitesox games for decades and specialized in shooting all players from visiting teams. You can find a lot of players that had brief appearences on a team. I bought a couple Tony Larussa Cubs photos from him. (Larussa spent the last week of his playing career with the Cubs). Prices are good and they should be made from his original negatives so the quality will be good.
