No, we'd call that propaganda as well.

It's not that "everything Russian is propaganda" it's that under the Soviet Union at the time these were produced there was a specific agenda and ideology intended to be propagated by the state and funded by it. And under that regime, if you made a holiday postcard showing a drunk Lenin and Stalin arm in arm staggering down a snowy street and tried to distribute it as "art" you would have likely ended up in a re-education facility. Context is relevant to the terminology here.
