What is this font ?

LT Oksana  Vorgeschlagen von LaurenRuth 


Futura Light  Vorgeschlagen von lolobeber 

Thx !

I'm not sure.
Look at the "0" here : http://i.imgur.com/Nj7BN.jpg

You are welcome. It is LT Oksana,-- that "0" is an "old-style" version available as one of the special characters of the font. The extended (full) character map of the font can be seen at Abstract fonts: http://www.abstractfonts.com/font/15590

The old-style numerals including this "0" are found towards the bottom of the character map I have linked to.

Lauren, thanks for confirming this. Has the "1" been modified especially for (or by ?) Arte ? I couldn't find it in the character map

I'm wondering because they declare the font as "LT Oksana Light WIP".

The "1" looks like "Futura Light" font, isn't it ? But it's not "Futura"...
