3rd rarest Topps test issue behind 3D and Game

These are checklists for the plastic busts that they made in 1968.

Another write up from the almanac:
These two cards, which measure 2 1/18" x 4", were inserted one per 1968 topps Plak pack. Each checklist card featured all the players from each league that were available in the packs.

Essentially there are 4 checklist cards which comprise the set of 24. Each checklist has 6 photos on each card.

For some strange reason, beckett lists the checklists twice. Once under the busts as:

NNO Checklist card 1-12 40.00 80.00
NNO Checklist card 13-24 40.00 80.00

and also lists them again separately as
1 and 2. They list these as 800.00 each on the high side and 400 on the low. The cards pictured in the auction I believe are checklist #2.

Hope this info helps. They seem pretty rare since they're already over 3x book value.
