Interesting. This picture is going in a bunch of different stylistic directions at once. I don't recognize the specific type of the aircraft, but its style and the clothes the airmen are wearing are very evocative of World War I; but the character in the foreground seems to have a WWII-pattern Thompson gun, while her battle dress and gear have kind of a Wehrmacht Panzergrenadier vibe going on.
OOZ662 said: that gullwing down to the cockpit doesn't seem fitting of biplane design.
Some of the biplanes utilized the gull wing design, for instance Soviet I-153 and early versions of I-15. The bomber in the picture is likely fictional, although it seems to take design cues from WW1 planes (e.g. Gotha G.III / Gotha G.IV, which, notably, also used the "pusher" propellers).

I forgot to include the word "bomber," sorry. Heavy biplane designs pretty much stuck to straight wings, one attached to the fuselage and one either over or under it.
