The Integral Booklets of the 1967-1973 Centennial Issue Part 1
One significant fact has been brought to my attention by Mr. Eirwyn Jones, a specialist from the UK. He sent me an article from the February 1970 edition of Maple Leaves, which contains some interesting comments about how the booklets were actually produced. Apparently, the integral booklets were produced using continuous rolls of stamps and rolls of covers. The selvage tabs were moistened and attached to the cover stock in pre-determined positions, and the card stock was scored to facilitate folding (rouletted actually). A cross cutter, guided by an electric eye, would cut the booklets apart as they were printed, and then the were folded. This stands in sharp contrast to the method used for producing stapled booklets, in which the cover material and stamps were printed in sheets, which were assembled, stapled and then cut apart. This new method of production provides some explanation as to why there are never any cutting guidelines on either the booklet panes, or the covers.
It should be mentioned that the CBN did eventually acquire this technology too and used it to produce a single integral booklet: the OPAL booklet, which was issued in October 1970.
As I explained in last week's post, there is a large amount of scope to cover with these booklets, as the total number of basic integral booklets issued during the life of this issue was 16. I have decided to break it down into three parts:
- The perf. 10 integral booklets which were printed by the BABNC and issued between January 1968 and May 1970.
- The perf. 12.5 x 12 integral booklets which were printed by the BABNC and issued between December 1970 and August 1971, as well as the OPAL booklet.
- The booklets containing the 8c parliament, which were issued between December 1971 and August 1972, due to their immense complexity.
- A cream coloured stock, which shows very fine horizontal striations across the cover, that resembles ribbing.
- A smooth cream coloured stock that shows fine vertical dimples throughout the stock.
- A rough textured cream coloured stock that shows no ribbing.
The ribbed card stock. Look toward the top of the booklet cover to see the fine horizontal striations running across the cover. The third type of card stock with the rough surface looks identical to this except for the ribbing.
- Moving? Ask for free change of address cards?
- Avoid loss - use postal money orders.
The fine print is shown on the left, and the bolder, coarser print is shown on the right in this side-by-side scan of two booklets.
- The cutting error on the orange booklet in which the two labels are separated by a stamp, instead of being located adjacent to one another on the left side of the pane. This variety lists in Unitrade for $5,000.
- The hibrite paper on the 6c black pane, which lists in Unitrade for $4,500.
