what's the font please ??

Helvetica Neue Bold  Sugerida por rocamaco 

thanks :-)

that "S" is definitely not Helvetica

It is. It's just chopped. The rest of the curve fits Helvetica Neue...

aahh, ok why they did it to that poor letter?

Very close!

Still, how you came up with this font is incredible!

An ace in my sleeve waiting for SashiX...

Not, seriously, it's a banner of a design studio, so I also think is Helvetiva Neue making some substituions with one of its look alikes, to be more unique...

Yeah, looks like a Helvetica's "S", with some modifications of course, can do the trick (but still, I'm not 100% sure at that size)
