I think the term “rookie” has honestly just supplanted the word “earliest” for all facets of card collecting. I’m fine with it. And I’ve started to dabble in the non-sports “rookie” collecting thing as well, but am way behind Peter with respect to this niche and am not as stringent with the “rules”.
As for Michel Jackson, wouldn’t his 1969 Victoria Vedetten Parade pre-date the 1972 issue from the first post??
