Actually, I'm the guy who wrote the SCD article about the many Millers. If the OP is correct, and Phildelphia Bob was tentatively sold to the Cardinals in 1959, then I retract what I said about Topps getting things wrong. They may have meant that Miller to be who he was supposed to be.
They still messed up all the Bob Smiths from that time period, though...
