2.5x3.5". The 1963 Post Cereal Baseball consists of 200 cards. Post distributed the cards (six each) via the back panel of cereal boxes with the format very similar to earlier Post entries, with all of the player's statistics and photo printed on the front. The reverse of each card remained blank cardboard with a heavier stock. A slight design modification introduced rows of stars on either side of the card number and statistical heading.

Brooks Robinson played his entire 23-year MLB career w/the Baltimore Orioles (1955-1977), which still stands as the record for the longest career spent w/a single team in MLB history (tied w/Carl Yastrzemski). Nicknamed "The Human Vacuum Cleaner" or "Mr. Hoover," he is considered the greatest defensive third baseman in MLB history. An 18 time All-Star, two time World Series champ (1966, 1970) and 1970 World Series MVP, he won 16 consecutive Gold Glove Awards during his career. Robinson was elected to the Baseball HOF in 1983. The autograph is distinct w/decent placement across the middle. A review of the PSA/DNA pop report indicates that this signed copy is the only one graded at this level and remains the highest graded.
