Can anyone identify this typeface?

It’s on the banner used by Goebbels for his “Totaler Krieg” speech. Possibly it was just custom for the banner, but at the very least the letters mostly look like something I recognize but can’t name. The O and Ü look a bit wider than what I’m probably thinking of.

Here’s a photo from the speech:

Unfortunately, your link just goes to the search form, not the picture itself.

Do you mean this picture?

It’s very much like our modern typeface Optima, designed by Hermann Zapf in the 1950s, but chances are that the banner was hand lettered.

That’s the photo, Euryphaessa.
I think Optima was the one I was thinking of.

It’s not Optima. The round characters (O, U) are slightly squarish in the link, and the umlaut over the “U” is way wider than Optima.

Considering that Hermann Zapf didn’t design Optima until the 50s, I’d say this was a precursor to it. It certainly looks like Zapf’s humanist sans-serif work.
