What: Baseball Digest, September 1991
I can still remember buying this magazine right off the rack. It's a little dirty and the cover is scuffed up, but still a great reading copy.
Baseball Digest is still around although it's bigger now and in full color, and now only publishs 6 issues a year and digital content. It's also kind of pricey. Anyways Robin was featured in this fall issue and gets a 3 page spread talking about his accomplishments and his run up to his 3000th hit.
