Petr van Blokland's Proforma.

In the mid-'80s, Petr van Blokland designed Proforma for
Purup, a leading supplier of forms systems. Oldstyle structure
provides essential copyfit and legibility, leading ATypI to award
Petr the Charles Peignot prize for distinguished typographic
achievement. In 1995, Proforma was the only typeface nominated
for the Rotterdam Design Award.

thanks for the help on that one- i really like this typeface ALOT. the lower case g and the old style numbers.
