It says in the flash file that the font is DicSans74 150 wt.

To be precise, DicSans74 150 wt and DicSans74 300 wt are embedded in the flash file.

Dic Sans? To which foundry does it belong? And what is the font for the Moleskin logo?

Most probably custom.
Moleskine resembles Copperplate Gothic.

Molotro Type

Thank you.

Do you know which font is used for the logo and Passions title above?

passions could be Officina Sans

It's interesting to me to note that the DicSans shown in Atwe's link looks a bit different than the one on the book covers. Did anyone else think that too?

The shape of the 'a' in particular seems like a distinctive feature of the Moleskine lettering, but the 'a' in the PDF sample at Molotro Type seems not quite the same to me. I didn't examine other letters, but that one caught my eye.

I noticed the same. Could it be a case of homonymy, or a further customization.

It's not a case of homonymy.
They're different because the version uploaded on the website was an ongoing project
and it's not updated.

Dic Sans is available now.
