I think there's some misunderstanding regarding the original post. Are we talking about the booklets from the Star Spangled Banner stamps, or are we talking about an
IMPERFORATE booklet pane from that stamp series? (By imperforate, I am referring to no die cut separation between ANY of the stamps; booklet panes will typically have one or more imperforate sides which is normal.)
Here's a link to the series of stamps being referred to here. Since these stamps were not offered in Press Sheet format, I imagine a complete booklet pane without any die cuts whatsoever, would be quite collectible.
