Panes cut from the sheet?
The topic I thought was apparent, so booklet panes, not sheet stamp panes. Sorry not to be clear.
You can't mean the sheet of the original six cent stamp, C-25. It would be apparent that they were not panes from the booklet.
No, I didn't mean that. Booklet panes are not printed individually. Booklet stamp designs are laid out differently on the printing plate vs. the sheet stamp. I think there is still a picture of this in Scott Specialized.
Booklet covers in full sheets are printed about the same size, and everything in full sheet size is sorted and stacked in order: back cover, interleaving(I think), stamps, interleaving, stamps, front cover (or in the reverse order) for #BKC2. A large stack of these is trimmed into piles of booklets. They are separated into individual booklets. Then each one gets, in this case, two staples applied by machine. The extra labor is why a penny extra was charged for the booklet, 37c for the 2-booklet pane booklet.
It would have been easier just to take sheets trimmed into booklet panes and use those for FDCs. They do this today. For this, that would mean no staple holes in the selvage. In other words, somebody had to take apart booklets to make the FDCs in this case as evident by the staple holes. Somebody got tired of doing that with yours and just tore the 3 stamps out of the booklet.
Do you mean torn from the booklet at the top perforation?
So, no I did not, per all of the above.
There are booklet panes that missed/do not have staple holes in this period, maybe even C25a. It changed at some time where "no holes/no glue strip in selvage" became common, because booklet panes without a glue strip to attach it to a booklet cover were sold by USPS in the 1990s. It probably continues today.
