Just get it on BitTorrent. Don’t pay these swines for their Stalinist censorship.
I’ve got many of the cartoons on laserdisc. Jerry Beck ran into some resistance from MGM (before the MGM-Turner and WB libraries were merged in a giant corporate monopoly) but his releases were on the order of 1000 high end boxed sets being sold to adults with some discs (at least in the Loony Tunes cartoons sets) being specifically labeled “politically incorrect”.
I don’t know if Tex Avery’s Uncle Tom’s Cabana ever made it to US DVD (it was on laserdisc).
