We once got a glimpse of Supergirl's original application to work at Catco. Anyone recognize the font she used for her name?
It looks close to Century Gothic and Futura, but I don't think it's either. They look different when bold.
I think it's the same font used in the text too.

PT Sans  Suggested by APlaPi 

Title is 'Penumbra Sans'

And text looks like 'PT Sans'

Thank you, Mr. Font Detective! That looks exactly right.

For the body text, you are correct again. It looks like the 'PT Sans Pro Caption' variant (with serifs on the I).

Thank you, and happy New Year! I can now make my own copy of this important historical document!

Sure!
Happy new year for you too!
