Centuries ago, the Roman empire was alive and well thanks to Roman soldiers, who were partially paid for their labors in salt. Meanwhile, in the homeland of pepper, India was also being used as a commodity. These two spices have been intertwined for centuries, both for their value as currency and for their ability to season food. It is hard to consider one without the other.
Two typefaces that also compliment each other are Caecilia and Frutiger. PMN Caecilia is a rather romantic typeface, at least in origin. Dutch type designer Peter Matthia Noordzij created it in 1991 for Linotype and named the typeface after his wife Caecilia. His first sketches for the typeface were drawn in 1983, while he was still in college. This slab serif type is more warm and friendly than those that historically have been designed with a more geometric approach (Lubalin Graph for instance). Frutiger, on the other hand, was created by Adrian Frutiger in 1968 for use at the Charles de Gaulle Airport in Paris. Very legible and much friendlier than its ancestor Univers, it is clean, modern and unassuming. The typefaces intermingle well with each other. If you wanted to purchase the typefaces today, I wonder if you could barter for them by paying the foundry in salt and pepper?
