This is from Life Magazine 1953. This is a screenshot from the movie Helvetica. I know there weren't that many typefaces back then, but didn't match the common ones like Brody.
Portables looks like Stymie, Motorola looks like a modified version of Stymie bold condensed with squareish "O"s

"Look at the new" appears to be handwritten. Two different o's, t's, e's.

The t is different, my suggestion was kinda closer, I wasn't expecting to see more similar typefaces still.



That's what I thought, back in the day many of those were hand made, what a skill they had!
