The Fisk IA is not included in the traditional checklist, although it did appear briefly in an early SCD Catalog checklist, which is maybe why PSA slabs it.
I do not know if all the D sheet cards can be found with some black missing. An ebay seller that was promoting blackless D sheet cards coined the term, blacklessing. As seen in my first post in this thread, the A,C and C sheet cards can be found with "blacklessing" gray features ( transition cards where some black was still present )
I have one of the Fisk IA cards where some black ink is missing. Use the links to see bigger photos
