This was Howe's fourth season in the WHA and his last with the Houston Aeros, where he starred with his sons Mark and Marty.

Gordie Howe's 1942 Saskatoon Lions Midget Champions Plaque

Before Howe became a hockey legend, he developed his skills in the Saskatchewan minor league system, the listing says.

It has a few loose pieces, but has been with the Howe family ever since.
