I've never seen a sheet to back this up but I believe the first series CL is single-printed along with each of the other cards in that series. There are 132 cards in series 1 so a full sheet would have likely contained 2 of every card, no short prints or double prints. I think all the subsequent series CLs were double-printed, which explains why they seem much more common and have multiple variations. (Series 2 was 131 cards and CL3 was therefore double-printed, for example). So it wasn't actually short-printed so much as the other checklists being double-printed makes it seem so.

Indeed, #9 was the final card I needed to complete my set. High grade, well-centered ones seem especially hard to come by.
