Isn't Swiss just another version of Helvetica? Martin, the sample is (I assume) a printed piece, and depending on what they printed it on you can have alot of the counters fill in. Plus the sample might be old enough to be a photostat then printed. Once again a loss of type quality.

You're right, Swiss is derived from Helvetica, but Helvetica doesn't have the Black face which filled in the counters more. Italic filled them in even more.
