I can't imagine the Art Nouveau (style) style decoration on top of the leg being done in the '70s or '80s. Also the wear suggests quite an age to me. My guess is 20s or earlier, though I have very little expertise to back that up.

Without better photos and drawers, back and bottom it is impossible to tell. But yes, there was furniture like this produced in the 70’s and 80’s in oak as I had a desk almost identical that I purchased and finished. That is why you must inspect the entire piece to know the age and without the photos it could be 1920 or it could be 1980.
