Can Anyone Identify This Stamp?

I'm going through my collection and I could not find anything on this one. It says 'Gegen krieg und faschismus' which translates to 'Against war and fascism' so I'm guessing it's German. Any info would be highly appreciated!
Thanks - ed

Ed, certainly a cinderella. Maybe East Germany? Parts of it look more like an advert for Wonder-Woman...

Thanks tim, that helps a lot. You wouldn't have any idea on value would you?

Almost certainly less than not very much. Of interest though.

Looks like 1960s-early '70s (Vietnam War era) East German propaganda sticker. Not a postage stamp. Might be of value to the Association of Soviet Era Propaganda Sticker Collectors, which has perhaps 3 members. Then again it might not be of value even to them.

I exaggerate. You want to ask about it on the forum for cinderellas rather than here. People there could tell you what might be known about it.

I've seen that somewhere recently, but can't place it. It's an anti war cinderella, I know that much. Let me ruminate...

Ah, found it (on another forum - thanks Ryan!)

It's a tab that came attached to a 1963 East German semi postal.

Anti war and anti fascist.

Appears to be a commemorative cancel on the corner, for what its worth.
