Napo is a typeface family created by Isabella Ahmadzadeh for her graphic design thesis. It is a slab serif font that she developed in two basic weights (regular & bold) and for which she created a companion sans serif, Leon Regular. The family was then extended by Zetafonts to include four weights (light, regular, bold and extrabold) and italic versions for both Napo & Leon.
Thanks to the Zetafonts Type Foundry. The original Napo & Leon weights are COMPLETELY FREE to download, for both commercial and personal use, while you can find the whole family at Zetafonts. Scroll the page for the links!
