The story on this card
Colbert's 1966 Topps card catches him at the very start of his big-league path, before his power ever showed up in a box score: selected by Houston in the 1965 Rule 5 draft, he spent the season on the Astros' bench, appearing in 19 games without a hit. The card is a high number from the seventh and final series, a Rookie Stars issue that stands as his recognized rookie card, pairing him with fellow Astros farmhand Greg Sims, both shown in Houston uniforms as prospects still trying to find a role. A St. Louis-born slugger who became the expansion Padres' first star, averaging 30 homers a year from 1969-1973 and making three straight All-Star teams at first base.
Sims' only major league season came with the 1966 Houston Astros, appearing in seven games with one hit in six at-bats. His 1966 Topps #596 Rookie Stars card, part of the high-number seventh series, pairs him with fellow rookie Nate Colbert under the Astros banner - a recognized rookie card for both players. Switch-hitting outfielder who reached the majors with Houston in 1966 after coming over from Pittsburgh in the Rule 5 draft, collecting his only career hit off Terry Fox.
