I have some of these booklet stamps and I am a bit confused on the correct Scott catalog numbers for them.
First I have one booklet from 1967, which contains 2 panes and each with 5 stamps and a label. According to Scott each of these panes would be Scott #454a and Scott #457a. What I am wondering is if there is an actual Scott # for the entire booklet of the 2 panes as one Scott #?
I then have another 4 booklets from around the same period, but each of these contains only 1 pane per booklet. Again, I am wondering if there is a Scott # for each of these as booklets or if the Scott numbers are again just based upon the individual panes themselves?
Below is a scan of the 4 booklets in question:
