Is vintage porn from reputable studios safe?

Is vintage porn from reputable studios safe? I found out that in the 60s and 70s, pornography with underage (below 18) people was "legal." So I was wondering, are studios like Colt Studio Group, Falcon Studios, and Catalina Video Distributors, which were founded in the late 60s, safe to watch? I even read that videos from before 1995 were exempt from the 2257 law, and that weirded me out a lot.
I really don't want to accidentally see something illegal, so should I just avoid watching anything from these sites, or are they safe today because of their reputation?

Actors from studios like Colt Studio, Falcon Studios and Catalina are mostly males in their prime, very masculine. A few blonds maybe a little younger but I don't think there were any teenagers under the legal age.

mike18 is a studio from early 2000s that has legal twinks but they look like jailbait.
