Ah, the crocodile.
This Tupolev ANT-9 which went into production in 1933 as "PS-9" (passazhirskiy samolot = passenger airplane).
Two ANT-9 were modified for propaganda air unit 'Maxim Gorky', named after different newspapers and magazines, with this particular one named after the satirical magazine "Crocodile".
The reptile-like nose was made of plywood.
