Transamerica Corporation, an insurance company, purchased United Artists in 1967. Any UA releases afterward had a version of this title.
Just about anything UA released had this title, including the DePatie-Freleng cartoons. Any DFE cartoons released to theatres after 1967 (or '68) had this title appear before the credits. They were still present when they were syndicated to television until 1981 when Transamerica sold United Artists to MGM. The logo was replaced with a "spinning UA" logo and that got spliced into the 16mm negatives for the cartoons that was still available for syndication.
It's relatively hard to find a 16mm print of a DFE cartoon with this logo intact (it's either the spinning UA logo or the logo is spliced out altogether), although I did find a few over the years.
