Same photo, better copy at
http://www.militaryphotos.net/forums/showthread.php?180530-Workers%92%96Peasants%92-Red-Army-(RKKA)-1918-1946/page24Profile from 'Yakovlev Yak-9U&P' book by Robert Panek
The plane belonged to the elite 151 giap. Inscription on nose reads "Venskiy" and means "Viennese" because regiments full name was
151-й гвардейский истребительный авиационный Венский Краснознаменный ордена Богдана Хмельницкого полк (
151st Guards, Viennese, of the Order of the Red Banner, of the Order of Bogdan Hmelnitski Fighter Aviation Regiment).
Pilot standing on the wing is Kizim, but according to D. Karlenko who interviewed him,
in Kizim's own words this wasn't his plane.
Internet sources usually locate this photo to Yambol airfield in Bulgaria. This is unlikely, 151 giap fought over Romania, Hungary, Czechoslovakia and Austria.
Photo was obviously made after the war somewhere in Central Europe.
Finally, note the silver border around the red star! This is an excellent example for
white fuselage number and silver bordered red star.
Cheers,
