Another interesting monochrome cover, this features a powerful documentary photograph of a street protest meeting in France probably in the 1960s credited to René Barthélémy (it partly wraps round onto the back cover). The use of strong red lettering for the word Révolutionnaires is an obvious move but nevertheless the titles really stand out. The album was a French production, bringing together arrangements of a number of political anthems from around the world. I’m not certain when it came out, but it looks like a Sixties cover to me. The same people also put out Chants de la Commune in 1971 and as that has a later catalogue number, this also suggests a 1960s date for the cover here. It has been reissued a couple of times and even made it to CD, while a couple of other countries put it out in less dramatic sleeves.
The label, Le Chant Du Monde, were founded in 1938 covering mostly French traditional music and are still going.

Oh god, that brings back memories – I had this record when I was in my teens – and rather idealistic (in the 70s). It got lost over the decades when moving.. I would have thought it came out in the 70s but with a late 60s spirit, but am likely to be wrong. Thanks for the memories, anyway!
Your comment prompted me to do a bit of digging on French music sites and two sellers over there put this to 1967, with editions in other European countries in the early 1970s. If things carry on the way they are it might be time for a vinyl re-release!
