I got my Leader Novelty Grove card from Bob Bostoff back in the late 1990's (I believe). He had a whole bunch of them for sale in the SCD at that time. He didn't have them labeled as Leader Novelty. They were labeled as "Small R316 cards", or something like that. I believe Bob's business name was Empire Sports. If any of you have some SCD magazine's sitting around from the late 1990's, you could probably cross reference his "sale list" to the checklist of Leader Novelty cards.
Here is my Grove Leader Novelty card.... Shown next to one of my W553 Grove cards...
