Ferrari 500 TR in Finland, probably in Koroistentie 8 in Helsinki, at the garage of Pentti Keinänen, who had several either for sale or for his own racing. My guess is this is the 1956 Ferrari 500 TR s/n 0610MDTR which was raced by Scuderia Askolin in 1957. The colors then, would be light metallic blue with dark blue stripe (used by Scuderia Askolin).
<hr>The caption in the original/source however, says this is a Scuderia Svezia car, the team owned by Tore Bjurström, and that he was in Helsinki as he had sold the car to Carl-Johan Askolin (not in this picture).  With Curt Lincolin as driver, this car became 4th overall in the Helsinki GP on 12 May 1957, the Eläintarhanajo racetrack (Djurgårdsloppet).<a rel="nofollow" class="external autonumber" href="http://www.barchetta.cc/english/All.Ferraris/Detail/0610MDTR.500TR.htm">[1]</a>
<hr>Seated, seems to be Curt Lincoln (behind wheel). The other in the car is Scuderia Svezia team mechanic Rune Bertilsson.  On the left is Carl-Otto Bremer (scarf hands in pocket), Tore Bjurstrøm (in a tweed coat with hat, head bent down), Pentti Keinänen (tweed suit, "military" hat, looking at photographer).  We also see Arthur Rafael ("Rafu") Huhta (military-like outfit) in the back. Leo Saarinen is mentioned as being on the right, he was a mechanic.<hr><p>The color of the car is unclear, but it was repainted light/dark blue with white pinstripe before the Helsinki GP race.
