I'd start with contacting Jim Stinson, followed by calls to Bill Corcoran (Tampa, FL), then Kevin Keating at Quality Autographs and Memorabilia of Virgina (www.qualityautographs.com).
I think you'll find the respective pricing structure increases as you move from Stinson, to Corcoran, to Keating. But as far as reputable, vintage baseball autograph dealers go, they are among the tops (in my opinion). I've been doing business with all three over the years.
Best of luck.
