Welcome to this great site along with a great bumnch of fellow collectors. I see you have decided on what to focus on initially. A good idea though you may find that you broaden your collecting goals as time goes on. Flea markets, Craigs list, on line sites such as sportlots.com are great places to quickly accumulate cards needed in your collection and trade bait for here on this site.
