There is no precise information about the owner of this car racing helmet, but it was used at the famous Eläintarha races in Helsinki between the 1940’s and 1960’s, probably in the F3 racing class.
The Eläintarha races took place on a narrow and winding circuit in the immediate vicinity of the Helsinki Olympic Stadium every May since 1932. They were discontinued after a deathly accident in 1963.
