Introduction to Unexploded Booklet Panes.
Expertising United States Unexploded Booklets by Tom Jacks
These booklets were first issued in 1900 with the 2 cent stamp Scott #279. Each booklet consisted of a front and back cover of cardboard stock and 2 or more panes of 6 stamps held together with one or two staples. The panes of stamps and the covers were cut at the same so the covers and the panes match. The cutting made two cut marks on the top and bottom of the booklet. For a booklet to be truly unexploded the cut marks on the covers and panes must align. Therefore, for a booklet to be truly unexploded the covers and the panes must align on all sides, the cut marks must align, and there must be no disturbance around the staples. If panes from another booklet were placed in covers from another booklet, the alignment of the sides and ends and the cut masks would probably not match, and this would be considered a made-up booklet. This has been observed in one particular airmail booklet where tagged panes have been replaced by untagged panes to form a more valuable booklet.
