Why no "In Memoriam" Cards?

[deweyinthehall]

I just posted a mock-up of a 1964 Topps 7th series slit on another chain, and it features the Ken Hubbs memorial card.

I've often wondered why Topps only ever issued an "In Memoriam" card in 1964 for Ken Hubbs and never again.

He died in mid-February of 1964 - would the players on the 7th series sheet already have been determined so that they knew they were planning on a Hubbs card already and this gave them an opportunity to still use that space for him?

When one thinks of others who have died during their careers, or even during the season, it seems like Topps would have marked their passing some way.

While I did collect cards in 79-80, I was still too young to understand things like this - for those who were mature collectors at that time, was there any expectation that there'd be a Munson tribute card of any kind in the 1980 set?

Per Wikipedia, 35 men have died during the Topps era while in their active careers - meaning, I suppose, they were at least under contract and on a 40-man roster?
