30c orange-red
50c chestnut
1p carmine-red
1.25 green
2.50 blue

06.10.1942 offset-litho, valid for postage till 31.08.1957

30c orange-red matt; coated; without watermark
50c chestnut matt; coated; rayos rectos (01.02.1949); without watermark
1p carmine-red matt; without watermark
2.50 blue without watermark

to be continued ....

The values of this series were issued 23.10.1940.

All had been printed in photogravure on the newly bought sheet-fed press Mailander. The paper used for this first part of the set was with an orthogonal watermark Sun+AЯ (transposed!) with a symmetrical paper wire and a direction of paper running parallel to the long side of the stamp "M".

The 30c and the 50c had been the stamps most frequently used - at least could be found in various appearances into the early 1950-ies...

30c photogravure:




50c photogravure:




1p25 only [!] in photogravure:

In 1942 the printing process was changed into offset-litho! The design had been changed quite a lot - mainly by the use of separate horizontal lines where before the plain background showed the photogravure screen:

Unclear is which paper had been used first for the stamps printed in offset-litho.

Probably the 30c and 50c on coated paper. The watermark is orthogonal, the paper wire is symmetrical, the direction of paper parallel to the long side of the stamp "M".

30c:




50c:




This type of paper had been used in 1943 for the 4th of June Revolution stamps (all face values, the 5c however also exists on other types of paper).

The coating looks very peculiar as you can often see the pattern of the wire from the front of the stamp!

to be continued ...

It is also possible that the 30c had been issued already in 1942 on orthogonal watermark, symmetrical paper wire and a direction of paper running parallel to the long side of the stamp "M":

30c:






to be continued ....

In 1945 the 30c, 50,c 1p and 2p50 were isssued on paper without watermark! Symmetrical paper wire, direction of paper running parallel to the long side of the stamp "M":

50c:




1p:





2p50:





All stamp are printed on transposed paper!

to be continued ....

In 1949 the 50c was isssued on paper with an orthogonal watermark with so-called straight rays (R.R. Nitidos)!
Asymmetrical paper wire, orthogonal watermark:

50c direction of paper running parallel to the long side of the stamp "M":




50c direction of paper running parallel to the short side of the stamp "m":





to be continued .....

In 1951 both the 30c and the 50c were isssued on paper with a parallel watermark so-called Rayado Vertical! Thus, an asymmetrical paper wire, direction of paper running parallel to the long side of the stamp "M".

30c:




50c:





to be continued ...

After 1951 both the 50c and the 1p were isssued on paper with an orthogonal watermark and an asymmetrical paper wire, the so-called Rayado horizontal! Thus, an asymmetrical paper wire, direction of paper running parallel to the short side of the stamp "M".

The dot in the N is in the other face values of that design too!

Hello Rein,

Good work! Have you continue with this series?

Alejandro!

I certainly will! But when?

Saludos, Rein

Rein,

I think there is a mistake, photogravure watermark is "m", not "M"...
