There's a big date discrepancy between the Uk comic with that front (1985) and this Russian one (1993) so it's possible that the inside is not the exact same stories as the UK one. The art is the same art, though. If you look at the bottom left it says Hasbro Industries UK (ltd). There are more than 200 mlp comics in English produced in the UK between 1985 and about 1993, so it's not easy to tell from the cover what stuff the Russian comic may or may not contain, or if the stories are even the same (you can maybe tell us that..?)
I can't remember but I think that Finnish and German pony comics use the same artwork but not necessarily the same content in the same magazine. Also, the German ones in particular have some lovely adverts for German release ponies like Raindrop, etc. So it would be interesting if the Russian one had anything like that, or what stories it featured.
1993 is after MLP ended in the US and right at the end of G1 in the UK, so I wonder how many of those there actually were or if it was a one off...
Thank you for sharing the existence of such a cool item
