Sorry,I didnt understand your question.You asking me:
1)About pictures of finnish POWs pictured directly in the detention camps?
2)About pictures of finnish POWs who voluntarily(or not) worked on some civilian or connected to military sites during the duration of war?
3)About pictures of finnish citizens detained during the duration of war and worked for support themselves?
Also,what time frame you interested in?
About the 1),I actualy have some pictures made by swedish representatives for the Red Cross,photographed circa 1944 in detention camp near Petrozavodsk.
