1948-52 Exhibits
 

We have had a number of discussions on the board regarding the baseball exhibits series issued from 1947-66. In many cases, the specific year(s) of issue for many of the cards can be determined. I am wondering if this is also the case for football/basketball/hockey exhibits that were issued from 1948-52? If so, what are the key factors to look at?

Especially interested in the dating of the Canadian Exhibits for hockey players.

Looking for year(s) of issue for these specific hockey players:

Bernie Geoffrion
Doug Harvey
Tom Johnson
Gordie Howe
Bert Olmstaed
Maurice Richard

Any assistance would be greatly appreciated.
