Yes, sorry about that, I misunderstood. You were talking about corduroy and peak lapels. Well, nowadays peak lapels are considered more formal than notch lapels (and I tend to agree at least in part) but this was not necessarily true in the past. In Golden era there were tweed jackets with peak lapels! However, to be honest I have never seen a corduroy jacket which dates before 1970, so I think that the jacket shown above can be safely assumed to be either from the 70s or from the late 90s.
