I have mentioned in the past about personalities appearing in trading cards, specifically people like Ken Jennings, Marc Summers, Austin Rogers, and James Holzhauer appearing in different Allen and Ginter releases since 2007.
I have also mentioned Donruss' long-gone Americana series, which had base cards, swatch cards, and autographs including Chuck Woolery, Wink, Bob Eubanks, Ed McMahon, John O'Hurley, and others.
A new-to-me series which is at The National Sports Collectors Convention, aka my home the last 4 days, is Leaf Pop Century, which has 4 autographed cards per box. Among people relevant to this board in this set are Carmen Electra, Alec Baldwin, Carrie Wilson, Corbin Bernsen, David Arquette, Dick Van Dyke, Gena Lee Nolan, Vicki Lawrence, and William Shatner.
I have had good luck with this product. My Facebook friends have seen what I have gotten.
