This is a genuine Soviet stamping, I think the idea was to show the heroic red army to the peasants (who were most likely illiterate but, given they were familiar with the icons of the church, used to getting stories from pictures. One can't help but speculate if the effect of this was a sudden upsurge in volunteers for the cavalry.
On a side note, I wonder if I could teach my horses to do that?
On second thoughts, having seen what short work they make of carrots, maybe not.
(Hat tip to BoingBoing for that one)
