No, actually, it doesn’t. Warsaw, for example, makes many western cities look dirty, old and outdated. Compare the Warsaw metro to the Parisian one sometime.

Even the clothing - such as the uniforms that people are wearing (military and civilian), the older fleet of cars present on the roads in many post-Eastern Bloc nations, the wonderful architecture from the pre-1990's still extant, and more, there are large similarities between the photos and the what things look like today.

Of course, things have changed, but to a large degree, the images presented have so much in common with the present.

Not sure where you've been but it looks nothing like the countries I've seen (Lithuania, Slovenia, Czechia, Slovakia, Croatia, Hungary, Former GDR)

Indistinguishable aside from the clothing.

The Eastern Bloc was a big bloc. Some countries are completely changed, some not that much.
