I know that the bold lettering is likely Optima or something related, but I'd like to know the other typeface.

Optima  Suggérée par Lancon 

The size and quality of the sample does not allow to be completely sure, but I believe it´s the same you said: Optima

I get that the bold is Optima. I'm asking about the other font.

I think it's all the same font.

Yeah. It's Optima.

Ah, okay. Thanks!
