Max WederSome of the original paintings from the 1930s are around, for National Chicle (football) and Diamond Stars (baseball). I saw the National Chicle at the National (Phil from the Bay area had them for sale) but I'd just be guessing at the medium.
As for the T206s, I don't have a clue what the medium was.
Howevever, I'd be interested in hearing about your art project. My spouse has done some larger paintings of early bb cards (http://ettinger.ca/lewis.html and http://www.flickr.com/photos/baseballart) and I'd be interested in others who have done or are doing the same.
