Perfect provenance here with embroidered labels of "TURN BACK THE CLOCK DAY / JUNE 19, 1991" on both the jersey front tail and pants waistband, along with an extensive LOA from authenticator Phil Wood who himself was in attendance at Memorial Stadium! The Rawlings garments worn by O's manager Johnny Oates are size 42 and size 35 respectively.

Wood's LOA says it all: "The Baltimore Orioles played their final season at Memorial Stadium, and on June 19, a day game on a Wednesday, trotted out uniforms that mimicked the uniforms they'd worn at home between 1966 and 1971, when the fabric would've been flannel, rather than polyester. It was nearly a full house that day: a crowd in excess of 44,000 was on hand to see the home team play the Minnesota Twins, the team they had defeated to win the 1969 and 1970 ALCS, advancing to the World Series each year. The Orioles took a 4-3 lead into the top of the 9th inning, and had relief ace Gregg Olson on the mound. It wasn't Olson's day, as he allowed 5 earned runs on 4 hits, 2 walks and 3 wild pitches, and the Twins won the game 8-4. I was the official scorer for the American League that day, and while I wasn't in the clubhouse to see it (I was doing the postgame paperwork required of the job) Olson took off his uniform, dropped it into a metal trash can and set it ablaze. Gregg Olson spent all or parts of 14 seasons in the major leagues, and I suspect this is the outing he'd call his worst. As previously mentioned, I was at the game where this uniform was worn. As manager, Johnny Oates' efforts would not cause any noticeable wear. It was a cool day in Baltimore—game-time temperature was 66 degrees—so there wasn't much opportunity for sweat stains. Rawlings did a solid job of replicating the vintage style, and this particular style of Orioles uniform doesn't show up very often. No issues in my expert opinion. Clearly authentic."
