Very early Mark McGwire autographed baseball from the 1984 Olympic Games when baseball first was introduced as exhibition sport. That ‘84 Olympic team was loaded - McGwire, Will Clark, Barry Larkin, and many more! This is a very early example of a McGwire signature before his break into the majors, ROY, and rookie HR record books.

Welcome to the Autograph Collecting Mantel Group! This group is all about the ink—whether you’re collecting on-card autos, signed memorabilia, or chasing in-person and mail-in autographs, you’ve found your people. From fresh-pulled rookie autos to vintage legends with the cleanest pen game, this is the spot to share, learn, and connect. Our goal is to build a fun, welcoming space for collectors at every level. Share your latest pickups, ask for authentication tips, talk through mail-in successes (and fails), and drop info on upcoming signings—both in-person and TTM (through the mail). You’ll find hobby news, signing announcements, mail day highlights, and plenty of discussion around pen types, photo choices, prep strategies, and more. We’re here for the stories behind the signatures just as much as the items themselves. Whether you’re a binder-builder, a slab-chaser, or just love getting a Sharpie in front of your favorite athlete—this group’s for you. Let’s keep things respectful, helpful, and collector-driven.
