I’ve been curious about these inserts (not just Mark Jeweler & National Diamond Sales) and catalogued the ones in my collection. I’ve listed them below, sorting by Insert Type, Year, Month, and Title.
The most interesting one to me is the Pizzazz insert in Marvel Two-in-One 39. I only have this 1 Pizzazz centerfold variant.
I found this copy on eBay of a CGC notation for a Pizzazz insert.
Pizzazz Variant
I think the Atari and CBS may have been standard or at least plentiful.
