Small threads in two late papers for the 20cSC

Rein noticed small threads in the clay (CL2A) and regular (1L1) papers. I find these as well, and in several colors.

A 1L1 example:





















a clay dark blue example,













and a second clay dark blue example.

A selection of 5pNOPs

The first specimen may be a plate variety, but I do not find a second specimen in my sample.









Additional 5pNOPs













including one canceled in 1950.

The most elusive 5p plate variety

The upper right stamp in this block has a scratch in the background that is very difficult to find.





The give-away is this outer edge break.





Here is a detail of the scratch.





In this comparison, I have blocked out the area around the scratch.

A 5p1L2 block showing repeated plate varieties

With this block we can postulate that the plate was made up in pair of rows and that some plate varieties come from the master dies. This pattern is found on other stamps of this series (the 10c Rivadavia Red and the 50c, for example).





The right side stamp in the first row has the same scratch...





.. as the right side stamp in the third row





The left side stamp in the second row is a common plate variety.

The 1p2D

The 1 peso value, like the 20c Large Format Cattle stamp (the 20cLC) was printed on the diffused (2D)and clear (2C) straight rays papers. This block was printed on the 2D paper.





Here is the back showing the watermark.





The lower right stamp has a plate scratch probably caused by placing the die into the printing cylinder.

Two 20 pesos blocks

The appeal of these high value blocks is unmistakable. Such a high face value was most likely paid for a post office box receipt.

This block is a 20p1E4.









This block is a 20pNGR.









The upper right stamp has a small indentation below the '20.'
