Had these been called out before? I see reference to a new sheet code and title arrangements I don't recall hearing about.
yes, it's been called out before.
I brought up this new sheet arrangement over 4 years ago when Toppsvault auctioned off a sheet showing the image negatives. That one not only actually has Bald and Tasters Choke in the sheet, but also had Bandache replaced by a Molten
My thought at the time was that whatever revision they were doing it was intended to be for the mail in poster.
But we still haven't seen a full color version of this sheet.
here's a pic of the original blue negative with the 2nd series stuck over some of the cards.
and I made an inverse to make it easy to see the Taster's Choke and Bald outlines (and pasted mini versions in to show the matching outlines)
