Did Lou Piniella appear on 4 Topps Rookie Cards?

Question

I think I remember him on Senators (65 or 66), Indians (68) &
the Pilots (69) and also the Royals (?)

Answer 1

Not four, no.

Piniella had one of the longest tenures from major league debut to conclusion of his rookie status -- he had a cuppa coffee in 1964 with Baltimore, another in 1968 with Cleveland, and finally played a full season in 1969 with the expansion Royals, winning the AL Rookie Of The Year Award.

His cards, however, do not match his major league playing time. He appeared on three basic Topps cards during the 1960s, each time paired with another prospect, as follows:

1964 Topps #167, Piniella and Mike Brumley, as Senators;
1968 Topps #16, Piniella and Richie Scheinblum, as Indians; and
1969 Topps #394, Piniella and Marv Staehle, as Pilots.

Lou finally got his own, single card in 1970, as a Royal.
