What is the story of this aircraft? From this page about nuclear bombers:

It seems out of Wild Wild West. What is this (Russian?) aircraft from another era? and what has been its use?

Update:We know now the image has been created using CG software, based on a real aircraft, that seems interesting and is by itself quite a mystery and technical feat that deserve explanations.
Why this design? gondolas, size, holes in wings, angular panels...? for apparently not so many people on-board.
Images of actual aircraft are found in answers. Also this one:

Thanks to @user52723a and @RonBeyer for providing details.
It is in fact fake but its most likely loosely based on a real plane. The Russian Kalinin K-7 contains a lot of the same design elements.

It appears that the real plane was also boarded from the landing gear area.

On a bit of a funny note this article mis-uses the photo you have linked in reference to the Kalinin K-7
