Why am i listing russian search engines?
Well, because you can use them to find copyright-free images to use here:
Quote from Wikipedia:
"...For example, according to Soviet (and now Russian) laws all works created before 1975 are in public domain. All films, photos, music and books created anywhere in the world before 1975 are public domain in Russia. Of course, you can't use on Wikipedia anything that was created before 1975 abroad (it would still be copyrighted outside of Russia), but you can use any image created in Soviet Union itself before 1975 (and sometimes after that)."
