Espana/Spain 1st & 2nd Issue?

I was looking to post some pictures for smauggie because he/she was looking for some stamps from Spain. Of course I know nothing about stamps from Spain I came across these two in particular. I wanted to see if this was a first and second issue? The perfs are different leading me to believe this.

There are actually 3 versions. The first (from 1939-1940) has a small imprint at the bottom "Sanchez Toda". The second is the one you showed below, with the large perforation (from 1939-1947). The third version has the small perforation gauge (13x13 1/2) and is from 1949-1953.

Toda example on 70c

As an aside, I have been fascinated by the icon
bottom of the shield LHS
An item with a double loop / bridge and a squiggly line

I think perhaps some form of early electric device and electric wire.
Any ideas?

"Yugo" and "nudo gordiano", coming from the Catolic Kings, XV century.

You can see a yoke (for harnessing bulls to a chariot) in Spanish "yugo". Then a bunch of arrows, in Spanish "flechas".
These two items were the symbols Ferdinand of Aragon and Isabel (Ysabel in old Spanish)of Castilla. Known in history as "the Catholic Kings", in the second half of 15th century.
Incidentally, this couple were the parents of Catherine of Aragon, first wife of Henry VIII and mother of Mary Tudor queen of England.

This simbology, together with Saint John's eagle, was recovered by Franco's fascist regime and widely used up to 1975.
