49 bowman mystery remains unsolved

[Webster]

The Red White and Blue Pack contained 5 Cards (as indicated on the wrapper):

Baker 119
Nicholson 76
Zoldak 78
Scarboro 140
Christman 121

All of these are from Series 3+4.
In the Orange and Green pack there were two cards from Series 2, with the others from 3 + 4.

IF these were not tampered with, it's POSSIBLE that the Orange and Green was used for Series 1 + 2, and they had some left over for the "transition" to series 3 and 4. The Red White and Blue was then used for series 3 + 4 and all subsequent series. (That would explain why they are the more common wrapper).

Ted Z. would know the answer in about 20 seconds. He loved the '49 Bowmans and had a massive collection, including a full set of the PCL players.

[Webster]

Ted’s (great) thread in the set can be found in the archives. That is the souce of the “series” breakdown above. However, what Ted refers to as series are actually individual sheet layouts. I believe he suggests that sheets (or “series”) 1 and 2 were issued together at the beginning of the season.
