Once Upon a Honeymoon

The credits that I can see while watching this as part of a Mystery Science Theater 3000 episode don't say so, but this must have been sponsored by Western Electric as a soft-sell for their telephones.

Our first clue is that the angels use modified telephone installer handsets - the kind with the dial on the back. Our next clue is how the phone is the cap of every room's imaginary redesign. Finally, it is the phone that gives the composer the idea for the song that springs the couple on to their honeymoon.

Common element: telephones.

There are similar short films extolling electricity, gas, cars, and, uh, cars (lots of cars). This one is tastefully done and doesn't quite hit you over the head with "phones come in colors now so order one today!" sensibility.
