Here are my customs of the missing cards plus the backs I made for them
Harry Brecheen and Pete Castiglione
Billy Cox and Joe Tipton
Ken Wood and Hoot Evers
Since the Evers original artwork hasn't been found, I used the artwork for the 1952 Bowman card and changed him from a Detroit Tiger into a Boston Red Sox.
Here are other 1953s that there was artwork done but never issued
Richie Ashburn, Max Lanier and Jim Suchecki
