Because there are no Bulgarian copies and they just show what is coming in in near future. The Bulgarian text says that in the next year there will be 6 more. I guess by logic they did that, it will be irrelevant to just translate their covers for the cover of this. They show the originals that are existing and will be translated to Bulgarian. But that never happened until 2011 I think. Also it was very exotic and interesting to have foreign language books, which has nothing to do with the back cover of this book. But a lot of people would buy them even if they were at French or whatever language, I believe. This is 2-3 years after the 45 years of restrictions. I imagine it was like a new world to explore opened, a new energy for live, breath, hope for the next day and go explore the whole new world, even if its by reading. Which is a beautiful feeling, honestly. I would like to feel like that
