This looks like a 1st re-release, probably from 1974 or 1975. Lalande Courbet, the printer, changed names many times from the 60s to the 80s. Forget Sonis, the name change is how you date a French poster printed by Lalande. The original printer name should read: Lalande Courbet, Wissous. From the early 70s to 1976, the name changed to Ets Lalande Courbet, which is what you have on your poster. Since the movie came out in 69-70 in France, it could have been re-released 5 years later. It is still a nice poster, but not from the 1st release. There is also a 2nd re-release from the mid-80s that reads SA Lalande Courbet. I know, identifying French posters can be complicated.
