20th Century Fox/Warner Bros. Logo (1974) (FAN-MADE) 

Here's a fan-made logos of 20th Century Fox & Warner Bros. Pictures in order.
It is possible that it was for the theatrical release of The Towering Inferno (1974) with the two distributions of 20th Century Fox & Warner Bros. Pictures that were never found in home video releases with the original logos.
I also used the 20th Century Fox/Lucasfilm music so it might fit the logo in order.
Credit goes to ‪@cassavetesforaday‬ for the video logos.
Videos used:
