Solve an alternate history puzzle

[Simon]

Hey to all!

I’d like to propose a little game. This animated gif is a depiction of an actual place in Moscow. Look for "Дом книги на Арбате" in google images to see the original building. However, the place on the gif exists in different reality, which is described in the upcoming alternate history novel - Moskau by G. Zotov.

There are six a.h. markers in that gif. Six things that are just not possible in today’s real Moscow. And I'll be happy to give a free copy of the book to the first one of you, who can list them all in the comment section.

All six markers could be found with simple observation and logic, but you can guess in comments and once a marker is guessed right – I’ll point it out. However, the winning comment must contain all six markers at once.

If you don't know where to start, just look closely at the picture. Or you can read the blurb for a hint:

The puzzle has me stumped but I bought the book for just US$1.99 just now.
