Propaganda On Stamps

I followed a thread this morning that dealt with the specific topic of the Hitler forgeries during WWII. It actually opened an entirely different train of thought - the use of postage stamps to forward larger political aims as opposed to those promoting a social cause or organization such as the Red Cross or Salvation Army. What a person might include would depend entirely on their own definition of "propaganda".
The scans below show a 1934 set issued by the USSR. I am fascinated by the use of the Editorial Cartoon format but know little about the reason for their issue nor about the person (they do all appear to be of a sameness) who produced the images. My own read of the subject matter would tend to suggest a strong anti-war theme though, from the date, I don't know whether it was general in scope or a more specifically anti-fascist theme. It's just a tad early for that though Mussolini was in power by this time as was Hitler.
Any information welcome.

















The whole theme does open up the much larger but easier to identify group of propaganda labels such as the one below from WWI France. Partial postmark does indicate that it was once on an envelope and being used as intended for a recruitment label more than anything.
