Actually, it is kind of a sad story.
Norman Joss died on Nov 21, 1977 at the age of 75. Two months later, on January 30, 1978, his father was finally elected to the Baseball Hall of Fame.
See:
Joss Kin Happy, Sad with his Election (The Blade Toledo, Feb 1, 1978)
There is a nice remembrance of Norman in the
Blade's April 27th edition, where he is described as a "modest man", "a soft-spoken fellow."
This article also mentions that Norman gave photos and momentos to the Baseball Hall of Fame in Cooperstown.
Does anyone here know anyone on the staff at the Baseball HOF who might be able to tell us more about their Joss memorabilia?
