that lower case "a" might help narrow it down... soooo many san-serif fonts to dig through...

Gill Sans Bold Italic  Sugerido por dg_angustias 

not gil-sans. look at the "a"

That "a" is this way because of a possible printing defect, it is not a typography feature

sorry, it's not a printing defect. I have hi-res eps files of the client's logo, but the font used wasn't embedded into file. It was done around 10 yrs ago, and he doesn't remember the font used.
