::@ Martin. According to the current Russian copyright law, any work which had been published in Russia (RSFSR) within 30 day period after its publication abroad is covered by the Russian copyright law. Therefore, it is not completely clear for me how the same work can be in PD in accordance with the Ukrainian laws and copyrighted in Russia, and what is the actual legal status of these photos in the USA. That is why I try to avoid usage of PD-Ukraine photos. Moreover, all Soviet photos currently used in English Wikipedia are either from American of German archives or PD-Ukraine.
