As we have already seen, the printing of stamps was a rotary letterpress milestone in the manufacture of our dear Seeders!
This upgrade has allowed, among other improvements, number and date sheets more accurately, thus facilitating their accounts.
The manufacture of books has also, but some years later, logically followed the fashion ...
printing books, remember, began by rotating the end of 1928.
Initially, only the numbering has been used, in the midst of the Sower stamp type strain at 50 c. red (type IV and type IIA 1931).
Secondly, the date was added in late 1932, but the type Sower had left his place, so the type Peace.
The only books rotary dated (and numbered) Sower type are those of 20 c. lilac-pink (Yvert No 190) and those of 30 c. dark red (Yvert No 360) which were printed respectively from April 21 to May 20, 1937 for 190
and 17 January to 8 February 1938 for the 360. These books
are among the most common, and therefore the most affordable type Sower. The amateur
corners dated and prints that I could not help trying to gather all known dates, but it is not easy to much! ...
few dates I miss, so if you're looking at such books dated, you know that I may be interested ...
In this regard, I want to launch another appeal: it is one of our readers not from when the Fab Shop Stamps stopped working on Saturdays? and May 1, then?
So far, my collection does not permit me to find the answer ...
**********
Remember also that a round cylinder-sale printed 2 sheets of 100 stamps, or 8 books of 20 stamps. Entries were twice round cylinder, so the bottom of each leaf-sale, and once every 4 books ...
* Both sale leaves were separated by an interval of the height of a stamp: This white space was partially occupied by the famous parallelograms that can be found on the edges of foil up and down.
Bottom left, we also printed sheet numbers, and bottom right, the time of printing. Hence the name "coin dated" assigned to the block of 4 lower right corner of the sheet bearing the date!
Multiple photos illustrating my previous articles can confirm this. These markings (Number and date) are most often black, but not always, you've seen! ...
* For books, one can not speak strictly speaking leaves, nor high nor low leaf, since the cut was made immediately upon manufacture, book by book, but the principle was the same: a space the height of a patch between 2 notebooks, which were eventually printed advertisements (rather than the famous parallelograms) but still the number to the left, and sometimes the date right.
However, the cutout between the notebooks was not always also regularly performed as it should be, and we can find these listings on both the leaf edge higher than the lower edge of sheet consisting of books.
Or straddling the two, and it is often the case, which often makes them unreadable ... Two books
contiguous when they are printed, so can each comprise half of the entries, once passed under the guillotine.
Their separation was indeed as cruel as definitive: the books were then sold by the piece, and even if a buyer took two at the counter of the Post Office, we does not necessarily sell it in two consecutive, much less forced two halves with registration ...
Imagine the luck it takes a collector to find and bring together two such books, after more than 70 years of separation! ...
Here are two examples that I wanted to introduce you today to illustrate my point: something made possible thanks to the extreme kindness of a great collector and friend, who kindly give me!
This, you will understand, of 8 blocks of 4 stamps, from four different booklets, superbly matched two by two.
With both their number, their date, cut in half by the guillotine, and located halfway between two consecutive books.
Pretty, no?
****************** I would, by comparison, to introduce you to another unique case in my collection: It is
a dated corner block of 4, from a sheet having mysteriously escaped the guillotine, and thus as having less leaf edge, the entire space between two consecutive sheets. Area measuring the exact height of a stamp bearing the same parallelograms and perforation of the stamps from the top of the next sheet!
spectacular too!
Never seen elsewhere!
Impossible for me to explain how that could happen is inexplicable!
Any suggestions would be welcome ...
I've never seen two sheets that were not separated by the machine after printing!
I do not even know that this can happen, and yet ...
Like what, once again, it was essential to know the methods of manufacture of our stamps, for the pleasure of finding and fully appreciate such beautiful pieces!
