I’ve come to think that Helvetica was never intended to be the cold, perfect, rational typeface it’s portrayed to be. There is a subtle warmth in the shapes that was lost over the years.
Lettering is a precise art and strictly subject to tradition. The ‘New Art ’ notion that you can make letters whatever shapes you like,is as foolish as the notion, if anyone has such a notion, that you can make houses any shapes you like. You can’t, unless you live all by yourself on a desert island.
