March 1940, a Finnish Bristol Blenheim Mk. IV bomber of the No. 44 Squadron refuelling at its air base on a frozen lake in Tikkakoski. On the fuselage is the swastika, which the Finnish Air Force had adopted as their symbol in 1918. Despite the likeness, it was not a Nazi design but was based on the personal owner; Eric von Rosen had donated the first aircraft to the Air Force.
