Would love to see a vintage section, I think it would be a great idea. I agree with everyone else, anything on vintage seems to get pushed down quick and looked over. I think it would help draw new members to the forums as well.
I recently inherited my step father's childhood collection and would love to display some of his stuff from the collection in this new forum...even the ones that were drawn on, had pinholes, and/or cut up.
You could have an "All Sports Vintage" under hobby talk and marketplace to see how well it does, maybe eventually do "Vintage" sub-forums under each sport in each section if an all sport becomes too congested.
Always looking to buy David Justice auto's, GU, and SP / SSP cards for my PC.
Also interested in John Smoltz and Greg Maddux auto's and GU cards.
